Thanks for reaching out, Test. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
The warning message "AudioMixer: stream timeout, ignoring" indicates a timeout occurred while attempting to retrieve audio data from the background audio playback stream in LiveKit. This suggests there may be an issue with the audio source, network stability, audio encoding compatibility, or the timeout setting itself. To troubleshoot: • Verify the audio source is working correctly and providing audio data. • Ensure network connection is stable with no significant packet loss or congestion. • Check that audio encoding is compatible with LiveKit's AudioMixer. • Try increasing the stream timeout value (default is 100ms) in the BackgroundAudioPlayer's 
stream_timeout_ms
parameter to see if it helps. If these steps do not resolve the issue, providing additional details about your setup and configuration may help diagnose further.

what is the suggested timeout value
t
Hey there! Let me break down the recommended stream timeout settings for you. For most use cases, LiveKit has some smart default values that work really well. With AudioMixer, they suggest keeping the stream_timeout_ms at 100 milliseconds, and for BackgroundAudioPlayer, it's 200 milliseconds. These aren't just random numbers – they've been carefully tested to give you the best balance between quick responsiveness and stable streaming. My advice? Start with these defaults and see how they work for you. If you're seeing any stream timeout warnings in your specific setup, then you might want to tweak things. But chances are, these settings will do the job perfectly! Here's a quick summary: • AudioMixer: 100 ms (default) • BackgroundAudioPlayer: 200 ms (default) Sources: livekit-rtc/tests/test_mixer.py | livekit-plugins/livekit-plugins-azure/livekit/plugins/azure/stt.py
