Three corner cases fixed:
1. Removing the currently-playing song caused the next song in the array
to be silently marked as "played" and skipped. Root cause: playedIndices
was updated in next() by marking currentIndex, but after remove() shifts
currentIndex, it pointed to the wrong song. Fix: mark songs as played
at play-time (in play/playAt/next/prev) instead of at next-request-time.
2. Using prev() in Random mode could cause a song to play twice — the
song navigated to via prev() was not recorded in playedIndices, so
next() could randomly select it again. Fix: prev() now marks the
returned song as played.
3. Switching to Random mode mid-playback could cause the current song to
repeat because setMode() cleared playedIndices without preserving the
currently-playing song. Fix: setMode() now re-adds currentIndex after
clearing.

In Random (shuffle) mode, the queue's next() method would return the same
song indefinitely when only one song was in the playlist, and never terminate
even with multiple songs. This happened because played songs were not tracked.
Added a playedIndices Set to track which songs have already been played in
Random mode. Once all songs have been played once, next() returns null to
stop playback — matching the expected behavior where Random plays each song
once in random order, while RandomLoop is the mode for infinite shuffling.

The ffmpeg-static npm package bundles a pre-compiled binary that passes
`ffmpeg -version` but crashes with SIGSEGV during actual audio processing
inside Docker containers (incompatible glibc/missing shared libraries).
Changes:
- Install system FFmpeg via apt-get in Docker production stage, which is
always compatible with the container runtime
- Reverse FFmpeg resolution priority in player.ts: prefer system FFmpeg,
fall back to ffmpeg-static (for non-Docker environments like Windows)
- Optimize Dockerfile multi-stage build: compile native modules (opus,
better-sqlite3) in builder stage and copy to production, eliminating
the need for build tools (python3, make, g++) in the production image
- Fix qq-music-api dependency from file:../qq-music-api (path outside
Docker build context, breaks npm ci) to npm registry ^2.2.10
https://claude.ai/code/session_01JAV8sBokoifKh4Hc8XbJws
The repo URL was pointing to the old `tsmusicbot.git` instead of the
actual repository name `teamspeak-music-bot.git`. Fixed both occurrences
(方式二 and 方式三 sections).
https://claude.ai/code/session_01VTscSE9PxD6qwF56WBMunQ
Repoints the `@sansenjian/qq-music-api` dependency from the public npm
release to a local fork at ../qq-music-api, which ships a corrected
getMusicPlay that:
- drops the hardcoded-sign GET path (no longer honored by QQ's vkey
server for VIP entitlement lookups)
- POSTs JSON directly to u.y.qq.com/cgi-bin/musicu.fcg (mirroring
the library's own getLyric.ts pattern)
- extracts qqmusic_key from the forwarded cookie and passes it as
`comm.authst` — the inline auth field the jsososo/QQMusicApi
reference implementation sets
- uses `ct: 19` (was 24) to match the community reference
For accounts that actually have entitlement to a given track, this
now returns the real VIP URL. For accounts that don't, QQ's vkey
server still returns result=104003 with empty purl — this is correct
server-side behavior and not a bug. Verified by observing the real
QQ Music web player on y.qq.com fall back to the same 30-second
preview on a logged-in account that lacks the specific track tier.
Supporting changes:
src/music/api-server.ts
The fork (v2.2.11) stopped auto-starting a Koa server on import —
it only listens when run as `require.main`. Explicitly import the
default Koa app and call .listen() with a server handle we can
clean up on shutdown. Without this fix, port 3200 silently fails
to bind and every QQ endpoint 502s.
src/music/qq.ts (getSongDetail)
The library's /getSongInfo endpoint returns upstream code 500001
because its param format no longer matches QQ's current API.
resolveAndPlay only needs `id` + `platform` to fetch a play URL,
so fall through to a minimal stub on /getSongInfo failure. This
unblocks /play-by-id and /add-by-id for QQ — they had been
returning "Song not found" for every QQ track regardless of
entitlement.
scripts/qq_browser_login.py
Visible-browser diagnostic tool that opens Chromium at y.qq.com,
auto-detects login via uin cookie poll, captures the full
post-login cookie set, tests it against /getMusicPlay for 稻香,
and writes the cookie to data/cookies/qq.json only if VIP
actually unlocks. On failure, dumps the full cookie to
data/cookies/qq.browser-capture.json for OAuth-vs-browser diff.
scripts/qq_verify_entitlement.py
Companion diagnostic: opens the real QQ Music web player at a
specific song's detail page so the user can manually click play
and verify whether their account has entitlement — independent
of any code path in this project. If the browser plays the full
song, HTTP 104003 is a request-signing issue; if the browser
also falls back to a 30-second preview, the account lacks the
tier/album purchase and no code fix can change that.

QR login against QQ Music has been silently broken: every call to
checkQrCodeStatus returned "expired", so the scan-and-confirm cycle
never completed even when the user successfully scanned the code. The
root cause was four independent bugs in our wrapper talking past the
library's actual HTTP shape.
1. getQrCode lost ptqrtoken.
/getQQLoginQr returns { img, qrsig, ptqrtoken }, but we stored only
one of them in the single `key` field (picking qrsig, falling back
to ptqrtoken). The polling endpoint needs BOTH — passing only one
fails with 400 "参数错误". Fix: pack both into the opaque `key` as
"qrsig|ptqrtoken" and split on the receive side.
2. checkQrCodeStatus used GET.
@sansenjian/qq-music-api 2.x registers /checkQQLoginQr as POST only
(router.js: `router.post('/checkQQLoginQr', ...)`). GET returns 405
Method Not Allowed, axios throws, the catch returns "expired".
Fix: api.post(url, null, { params }).
3. checkQrCodeStatus parsed the wrong response shape.
The endpoint uses customResponse, not successResponse, so axios sees
the body directly (no { response: ... } wrapper). The actual shape
for each state is:
waiting: { isOk: false, refresh: false, message: '未扫描二维码' }
expired: { isOk: false, refresh: true, message: '二维码已失效' }
success: { isOk: true, message: '登录成功', session: { cookie } }
We were looking for a numeric `code === 0/1/2` field that does not
exist, so every state fell through to "expired". Fix: switch on
isOk / refresh / message.
4. Cookie read from the wrong path on success.
On isOk=true the cookie lives at res.data.session.cookie, not
res.data.cookie — so even if everything else had worked, the cookie
would never have been saved. Fix: read session.cookie.
Also rewrites getAuthStatus to actually validate the cookie:
5. getAuthStatus hit a non-validating endpoint.
/getUserAvatar is not registered on the library's main router; the
real route is /user/getUserAvatar, and even that just builds a
static avatar URL from a uin without round-tripping through QQ
Music with the cookie. The result: the bot happily persisted any
user-supplied cookie to disk and sent it on every request while
every downstream login check returned "not logged in". Fix: parse
uin from the cookie, call /user/getUserPlaylists (which actually
hits QQ Music with the cookie), and derive the avatar URL from the
uin via q.qlogo.cn/headimg_dl.
This is the same getAuthStatus fix that was sitting on the
claude/bot-shutdown-disconnect-cwFvF branch, now combined with the
QR login repairs.
Verification:
- tsc --noEmit clean
- vitest: 93/93 pass
- Live: POST /api/auth/qrcode platform=qq returns both tokens packed
into `key`; polling a freshly-issued QR returns {"status":"waiting"}
instead of the old {"status":"expired"}; raw library response is
{"isOk":false,"refresh":false,"message":"未扫描二维码"} as expected.
- Regression: netease and bilibili QR flows still produce non-empty
qrUrl/key — no collateral damage to the other providers.

- Delete the top-of-file "dev 分支" warning block and the whole
"dev 分支最新变更" section. Content that was only a dev-branch
changelog is now folded into the new "更新日志" section.
- Reword the identity migration warning in the upgrade section so it
refers to the library version (0.1.x → 0.2.x) instead of a specific
dev-branch commit hash, and add a "how to tell if you need to
migrate" note for users on fresh installs.
- Remove "`dev` 分支已实现" phrasing from the TS6 FAQ entry.
- Add a new "更新日志" section before "致谢" that summarizes recent
changes in four buckets — protocol/stability, HTTP API hardening,
connection state consistency, and feature improvements — plus a
brief historical milestones block pointing at git log for full
history.

Adds a prominent warning block at the top of the "更新升级" section
explaining why identities generated by 0.1.0 are incompatible with
0.2.x's corrected P-256 DER encoding path, and how to migrate: clear
the identity column so the next start regenerates a fresh key.
Covers three scenarios:
- TS3 + old identity: mostly still works (TS3 is tolerant)
- TS6 + old identity: must clear — otherwise handshake hangs at
`received initivexpand2`
- After clearing: server groups must be re-granted to the new UID once
Also adds a back-reference at the end of the upgrade section so
readers skimming per-platform instructions don't miss the migration.

Version 0.2.1 ships a universal clientinit format that works natively
against both TS3 and TS6 servers:
client_version: "3.?.? [Build: 5680278000]"
client_version_sign: DX5NIYLvfJEUjuIbCidnoeozxIDRRkpq3I9vVMBmE9L2qnekOo
BzSenkzsg2lC9CMv8K5hkEzhr2TYUYSwUXCg==
The old ts6-compat.ts workaround (monkey-patching handler.sendPacket to
rewrite clientinit's client_version to "3.6.2") is now actively wrong:
it replaces the library's new correct version/signature pair with a
stale one that TS6 servers reject, which is why the first 0.2.1 TS6
handshake attempt still hung at `received initivexpand2`.
Changes:
- package.json: "@honeybbq/teamspeak-client": "^0.1.0" -> "^0.2.1"
- src/ts-protocol/client.ts: remove patchClientInitVersion import and
the sendPacket monkey-patch block. Leave an inline comment so anyone
reading the git blame understands why the shim is gone.
- Delete src/ts-protocol/ts6-compat.ts and ts6-compat.test.ts — no
callers remain.
Other 0.2.x notes worth knowing (no code change here, just documenting):
- ClientOptions gained serverPassword / defaultChannel /
defaultChannelPassword that are sent DURING clientinit. We still call
our own joinChannel() post-connect because the existing flow works
and switching is an orthogonal refactor.
- 0.1.1 contains the P-256 DER encoding fix (PR #5 by ZHANGTIANYAO1).
Identities generated by 0.1.0 are cryptographically incompatible with
0.2.x's corrected handshake path — a bot whose identity column was
populated before this upgrade will hang at `received initivexpand2`
and fall through the 15s connect deadline. Workaround: clear the
identity column so the next start generates a fresh key. Server
groups assigned to the old UID must be re-granted once against the
new one.
Verification:
- tsc --noEmit clean
- vitest: 93/93 unit tests pass (1 test file removed with ts6-compat)
- scripts/test_full_feature.py against a local TS6 server: 51/51 pass,
including handshake, voice playback, identity persistence, WebSocket
stateChange broadcasts, and all corner-case regressions.
- Live: bot connected to TS6 in ~80ms after identity regeneration,
played NetEase audio through the voice channel, clean stop.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Major bug fixes and corner-case hardening across the backend, plus a
comprehensive feature test suite. All 94 unit tests + 51 integration
tests pass against a local TS3 server.
Lifecycle & state consistency
-----------------------------
- Bug A: startBot() now wraps connect() in a 15s deadline. A hung TS
handshake no longer blocks the /start HTTP call forever; the failing
instance is torn down and the caller gets a clean 500.
- Bug B: executeCommand rejects audio-dispatching commands (play, add,
next, skip, prev, playlist, album, fm) when the bot is disconnected.
Config-only commands (vol, mode, clear, stop, queue, now, lyrics)
still work so the UI stays usable while offline.
- Bug C: the tsClient 'disconnected' handler always clears player state
now, even when connect() never completed. A separate disconnectEmitted
flag guards duplicate external event emission. Previously an orphaned
connect attempt that idle-timed-out would leave playing=true forever.
- resolveAndPlay re-checks this.connected AFTER the URL-resolve await so
a stop() during the network call can't spawn ffmpeg on a disconnected
bot.
- connect() throws if disconnect() fired during the handshake await,
preventing a concurrent stop from being overwritten by a late connected
flag flip.
- startBot always disconnects the outgoing BotInstance before creating
a replacement, covering the mid-handshake case where isConnected()
still returned false but the library client was live.
- startBot now reuses the stored identity so server groups granted to
the bot survive restarts (was regenerating a fresh UID each time).
WebSocket reliability
---------------------
- BotManager extends EventEmitter and emits 'botInstance' whenever a
new instance is created. websocket.ts listens and re-attaches its
stateChange / connected / disconnected listeners immediately, fixing
the bug where player-bar UI never updated until manual refresh.
- attachedBots map now stores the BotInstance reference and detaches
stale listeners when the instance is replaced. Safety-net interval
(5s) also reconciles to catch anything missed.
- removeBot emits 'botInstanceRemoved' -> WS broadcasts a new
{type:"botRemoved", botId} message. Client drops the bot from its
local store instead of showing it as permanently offline.
HTTP input validation
---------------------
- /volume rejects non-number, NaN, Infinity, and out-of-range values
with a proper 400 instead of a 200 OK wrapping a usage-text string.
- /mode rejects anything not in {seq, loop, random, rloop} with 400.
- /seek rejects NaN / Infinity / negative (previously NaN slipped
through typeof==="number" and poisoned seekOffset).
- /play-at validates index < queue.size() BEFORE stopping current
playback (was silently killing the current song on invalid input).
- /play, /add, /playlist, /play-by-id, /add-by-id, /play-playlist
all honour platform=youtube now (previously fell through to netease
and silently played the wrong platform).
YouTube made truly optional
---------------------------
- Lazy checkYtDlpAvailable() runs `yt-dlp --version` once, caches only
positive results so users can install yt-dlp mid-run and have it
picked up without a restart.
- getAuthStatus() returns loggedIn=false with nickname
"YouTube (yt-dlp not installed)" when the binary is missing. UI can
grey out YouTube instead of silently returning empty searches.
- findYtDlp() picks .exe on win32 and bare binary elsewhere.
- /auth/status?platform=youtube now routes to the YouTube provider
instead of falling through to NetEase and leaking the NetEase
user's nickname + avatar.
- /auth/cookie rejects platform=youtube with 400 instead of clobbering
the NetEase cookie entry.
- README documents yt-dlp install paths (bin/ local vs PATH) and adds
a dedicated "Optional: YouTube source" section.
Bot Selector UI
---------------
- New power button in each row of the dropdown with play-state-aware
styling: disabled + wait-cursor during API call, green highlight when
connected, greys out when the bot is offline.
- Dropdown always visible when >=1 bot exists, bigger font + padding.
Queue correctness
-----------------
- PlayQueue.remove(current) now decrements currentIndex so next() in
sequential mode advances to the shifted song. Previously removing
the currently-playing track silently skipped the next track because
current() falsely reported it as active and next() then incremented
past it.
Vote-skip hardening
-------------------
- cmdVote: needed threshold is Math.max(1, ceil(users/2)) so a single
voter in an empty channel can't unanimously pass a vote with
needed=0.
- resolveAndPlay clears voteSkipUsers on every new track load so votes
can't leak across songs via cmdPlay/cmdPlaylist/cmdAlbum/cmdFm paths.
cmdAdd parity
-------------
- cmdAdd auto-plays the newly-added song if the player was idle,
matching /api/player/:id/add-by-id behaviour. Previously add'ing to
an empty queue on a connected+idle bot silently enqueued without
starting playback.
Test suite
----------
- scripts/test_full_feature.py — 51 tests across 10 groups exercising
every HTTP endpoint, WebSocket broadcasts, all music providers, bot
lifecycle, disconnected-state corners, seek validation, input
validation, and the main race conditions. Captures and restores the
target bot's initial state. Resilient to TS3 anti-flood via retry
with exponential backoff. Runs against a real local TS3 server.
- scripts/test_rapid_cycle.py — Bugs A/B/C regressions
- scripts/test_corner_cases.py — disconnect-during-connect race, config
commands while disconnected, etc.
- scripts/test_more_corners.py — resolveAndPlay race, seek NaN
- scripts/test_power_button.py — E2E for the new power button
- scripts/test_bot_remove.py — E2E for WS botRemoved broadcast
- scripts/test_playbar.py — player bar auto-show regression (updated
to restore bot state on exit)
- scripts/test_multibot.py — two-bot concurrent playback monitor
- src/audio/queue.test.ts — 4 new vitest cases for remove() edge cases

startBot creates a fresh BotInstance but the WS layer keyed its listener
map by bot.id, so ensureAllBotsAttached skipped the new object and
stateChange events were never broadcast — the player bar only appeared
after a manual refresh. BotManager now extends EventEmitter and emits
"botInstance" whenever a new bot object is created; websocket.ts stores
the bot reference, detaches on replacement, and subscribes to the event
for immediate wiring.
Also enlarges the bot selector (padding 10×20, font 16, min-height 44,
bigger dot/chevron/state icons, wider name) and adds Playwright repro
scripts for the player bar bug and navbar sizing check.

When starting a bot, re-instantiate BotInstance from latest database
config so changes to host, nickname, channel, protocol etc. take
effect immediately without requiring a full app restart.
Adds a "play" script as an alias for "start" (both run `node dist/index.js`).
This resolves confusion where users might try `npm run play` based on the
bot's music-playing nature.
Fixes#11https://claude.ai/code/session_01GC6qsKsmiroNkruLENDhPq
Root cause: on Docker restart, loadSavedBots() unconditionally connected
ALL saved bots regardless of autoStart flag, causing a rapid
connect/disconnect loop. Additionally, bot identities were regenerated
on every restart, causing TS server conflicts with stale sessions.
Changes:
- loadSavedBots() now only auto-connects bots with autoStart=true
- startBot/stopBot persist autoStart state so restart behavior matches
user intent
- Bot TS3 identity is persisted to database and reused across restarts
- Database schema migrated to include identity column
- TS3Client.connect() cleans up existing connection before reconnecting
- Stagger bot connections by 1s to avoid overwhelming the TS server
https://claude.ai/code/session_01L2kEV2M1QFWMCyPtLU5LgC
Two issues fixed:
1. Cross-platform ffmpeg-static resolution: skip Windows .exe paths on Linux
and always fall back to "ffmpeg" instead of a known-bad path
2. Prevent trackEnd cascade when ffmpeg spawn fails — track consecutive
failures and stop after 3, suppressing trackEnd on spawn errors
https://claude.ai/code/session_013vHRF8BbDGjZLqheFS85Q6
1. Move TS6 handler patch to after client.connect() — the library's
connect() internally replaces handler via #S(), discarding any
patch applied beforehand. Patching after connect() is safe because
clientinit is sent in async message callbacks after Init1 round-trips.
2. Preserve detectedProtocol across reconnect — disconnect() resets it
to "unknown", causing the TS6 patch to be skipped on reconnect.
3. Prevent double "disconnected" event in BotInstance — disconnect()
emitted it directly AND the async TS3Client disconnect triggered
another through the event chain.
4. Guard playNext() against running after disconnect — check connected
flag to avoid ghost queue processing.
5. Fix UDP error timer leak — clear previous timer before setting a new
one to prevent accumulation.
6. Fix isPortFree() FD leak — close the test server on error path.
https://claude.ai/code/session_01QzvMLUT3UkhsffShcY1qzD
The @honeybbq/teamspeak-client library sends clientinit directly via
handler.sendPacket() during the handshake, bypassing the commandMiddleware
chain entirely. This meant the ts6VersionMiddleware never intercepted the
handshake clientinit, so TS6 servers always received version 3.5.3 and
silently rejected it (never responding with initserver), causing idle timeout.
Fix: monkey-patch handler.sendPacket() to intercept clientinit packets and
upgrade the version to 3.6.2 before they're sent over the wire.
https://claude.ai/code/session_01QzvMLUT3UkhsffShcY1qzD
The script previously checked for a dist/ directory and failed with
"Please run this script from the TSMusicBot source directory after
building" — requiring users to manually build before installing.
Now the script:
- Resolves project root from script location (works from any cwd)
- Installs build tools (build-essential/gcc) for native modules
- Runs npm install + npm run build automatically
- Copies built artifacts to /opt/tsmusicbot
- Creates data directory for runtime files
- Adds journalctl command to the help output
https://claude.ai/code/session_016WhH58avUD9xy2dgADJgTh
- Add dev branch notice and changelog section at the top
- Add TS3/TS6 badges
- Document new protocol modules (protocol-detect, http-query, ts6-compat)
- List all bug fixes in dev branch
- Update architecture diagram with new ts-protocol files
- Add TS6 Server FAQ entry
- Credit NeteaseTSBot for TS6 protocol reference
https://claude.ai/code/session_016WhH58avUD9xy2dgADJgTh
clientinit compatibility:
- Analyzed @honeybbq/teamspeak-client's clientinit: it already sends a
clean 14-field payload without problematic fields (no badges,
integrations, security_hash, etc.)
- The key difference vs NeteaseTSBot is client_version: our library
sends 3.5.3, NeteaseTSBot sends 3.6.2. TS6 servers may reject
older versions.
- Add ts6-compat.ts with CommandMiddleware that patches clientinit
to use version 3.6.2 + matching ECDSA signature when connecting
to detected TS6 servers
- Middleware is automatically applied when detectedProtocol === "ts6"
Pre-existing bug fix:
- Fix playNext() in instance.ts where successful retry still fell
through to player.stop(), killing the just-started playback
https://claude.ai/code/session_016WhH58avUD9xy2dgADJgTh
Critical:
- Persist serverProtocol/ts6ApiKey in database schema so TS6 config
survives restarts (added columns + manager save/load)
Medium:
- Clear udpErrorTimer on disconnect to prevent memory leak and stale
log messages from firing after teardown
- Guard against double connect() by disconnecting old client first
- Add settled guard in TS6HttpQuery.request() to prevent double
reject when both res error and req error fire
- Add res.on("error") handler to TS6HttpQuery response stream
Low:
- Cap probeTS3Query banner buffer at 256 bytes to prevent memory abuse
from non-TS3 services sending large data on port 10011
- Remove unnecessary EventEmitter inheritance from TS6HttpQuery
- Update database test fixtures with new serverProtocol/ts6ApiKey fields
https://claude.ai/code/session_016WhH58avUD9xy2dgADJgTh
- Fix double-resolve race in probeTS3Query (data event vs connect timer)
by guarding with a resolved flag
- Fix double-resolve in probeTS6HttpQuery similarly
- Support custom query ports in detectServerProtocol via DetectOptions
- Clean up httpQuery and detectedProtocol on disconnect()
- Add res.on("error") handler in HTTP Query client to avoid unhandled errors
- Improve logging: warn with actionable message when protocol is unknown
https://claude.ai/code/session_016WhH58avUD9xy2dgADJgTh
The @honeybbq/teamspeak-client library already handles TS6 license block
type 8 (Ts5Server) in its handshake, so voice connections work with both
TS3 and TS6 servers. This commit adds the surrounding infrastructure:
- protocol-detect.ts: Auto-detect server type by probing TS3 ServerQuery
(port 10011) and TS6 HTTP Query (port 10080) in parallel
- http-query.ts: TS6 HTTP Query client replacing the raw-TCP ServerQuery
that TS6 servers no longer support (ports 10080/10443)
- client.ts: Protocol-aware connection with auto-detection, TS6 HTTP
Query setup, and forced protocol override option
- manager.ts: Pass through serverProtocol and ts6ApiKey config options
- connection.ts: Mark legacy TS3 ServerQuery as deprecated for TS6
https://claude.ai/code/session_016WhH58avUD9xy2dgADJgTh
- Global uncaughtException/unhandledRejection handlers in index.ts
- FFmpeg stdout/stderr stream error handlers in player.ts
- HTTP server and WebSocket server error handlers in server.ts
- Safe WebSocket broadcast with try-catch in websocket.ts
- Catch async errors from textMessage handler in instance.ts
- Reset voiceFramesSent counter on reconnect in client.ts
https://claude.ai/code/session_01EjpEsC2GCsvwbu4n3XC8EE
The pino logger's ThreadStream was throwing unhandled EINTR errors
when FFmpeg child processes were spawned, crashing the entire bot.
Add an error handler to suppress EINTR and prevent process crashes.
https://claude.ai/code/session_01EjpEsC2GCsvwbu4n3XC8EE
The ffmpeg-static bundled binary was crashing immediately (exitCode: null,
no data produced). Now we run `ffmpeg -version` to verify the binary works
before selecting it, with automatic fallback to system ffmpeg.
Also logs ffmpeg binary path at info level and captures signal in close event.
https://claude.ai/code/session_01EjpEsC2GCsvwbu4n3XC8EE
Adds info-level logs at each stage of the audio pipeline to help
diagnose why playback produces no audible output:
- FFmpeg first PCM data received
- FFmpeg process exit code
- FFmpeg stderr (errors/HTTP/stream info at info level)
- First opus frame encoded and emitted
- First voice packet sent to TeamSpeak
- Error catching in frame encoding loop
