@KamilSucharski Thank you for reporting the issue. Unfortunately, we were not able to repo it. We have included a test application attempting to recreate the issue. If you can please modify it so that we can reproduce the issue using the test app, we can more easily fix the issue.
link to the test app is here
Also, just looking at what was posted, AudioSwitch doesn't need to be called to enable/disable an audiotrack. In fact, see what happens if AudioSwitch is enabled at app start up and disabled at app shutdown.

2 years ago @afalls-twilio Here are the results:
I'm not 100% sure what was the cause here, but I have a suspicion. The ugly while (true) in old line 193 was probably too agressive on the Schedulers.io() thread, which i imagine Twilio also uses and maybe it created some friction? I had issues with some network calls not going out of the app until I changed them to use Schedulers.newThread() instead of Schedulers.io() - at the time I suspected Twilio of hogging the thread to itself, but now I suspect both it and that volume indicator that was here.

2 years ago @KamilSucharski What are you attempting to do? It looks like the code you posted is creating an audio track just to calculate what the audio level in decibels. Would it be easier to make a custom audio device that calculated the decibels as it recorded the audio that is being sent to webrtc?

2 years ago @afalls-twilio It shows the users their mic volume before they join the call.
Description
When connecting to the room without microphone enabled we get a crash. This only happened on our Google Pixel devices. The stacktrace is not very helpful, as the relevant part looks to be
but there are no further details.
