Crashes and restarts on audio/video calls on some desices

[dluciv]

Hello. Thank you for this great application!

Hope this will help to make it even greater and improve its compatibility with different crazy devices.

I have some Android devices, and one of them gives a crash when trying to perform audio or video call. It is likely libjingle audio recorder initialization issue:

W/AudioPolicyManagerBase(  145): getInput() could not find profile for device 100000, samplingRate 44100, format 1,channelMask 0010
E/AudioRecord(32506): Could not get audio input for record source 7
E/AudioRecord-JNI(32506): Error creating AudioRecord instance: initialization check failed.

After crash, application shows splash screen (likely restarts).

See a bit more logs below.

My device is HighScreen Boost 1G (rebranded Innos D9), having:

• Android 4.1.2, kernel 3.4.0
• Qualcomm 8625 1.4 GHz (ARM v7)
• 1GB RAM

That's because 2 instances of webrtc::WebRtcAudioRecord were existed at the same time (maybe because 2 peer connections existed at the same time).
