[bug] `selectAudioInput` doesn't work on mobile

[bdlukaa]

Describe the bug

I can not change the audio input device.

To Reproduce

Call await room.room.setAudioInputDevice(device);.

Apparently this was disabled on #742, but I believe it should be enabled back.

On WebRTC, this feature is implemented on the Android side:

Expected behavior

The audio output device should be enabled on mobile platforms.
