Chrome on Android WebRTC volume slider doesnt work when using microphone

When I establish a WebRTC connection with output and input (video and microphone) on chrome for Android, when controlling the volume slider using hardware keys, I will get shown the volume for the STREAM_VOICE_CALL stream, which is not the right stream for the WebRTC. This make it impossible for the user to effectively control the volume.

I'm guessing this is happening because when I turn on the microphone (with getUserMedia), the system thinks i'm in a call.

Any ideas on how to fix this? Is it expected behavior or a chrome bug?

Thanks

Is that how it is built now? At least chromium issue 243506 tells the following:

Enable audio volume control on Android.

This is done by setting stream to VOICE which is the only stream type hooking up volume control automatically. It's required to use matching audio mode and stream type. Otherwise, the volume control doesn't work. That means we have to use same mode for both WebAudio and WebRTC. This leads to the change in audio_manager_android.cc which sets audio to communication mode so that OpenSL stream can use VOICE stream type to adjust volume.

Bold is added by me.
