A phone controller connected to a car often captures through the car's
Bluetooth microphone, which takes the audio focus away and makes the platform
pause the session. To let the platform offer another microphone instead, the
API gains a vocabulary for audio inputs:
- setAudioInputDevices(devices, activeDeviceId) reports the controller's audio
inputs and the device the current stream uses. It accepts the result of
enumerateDevices() as is and reduces each entry to { deviceId, label,
groupId }, since nothing else survives postMessage cloning usefully.
- onAudioInputDeviceChange(device_id) is called when the player picked another
microphone on the platform, so the game can reopen its stream on it.
- getUserMedia also sends microphoneRequested, which the platform correlates
with the audio focus it loses.
setAudioInputDevice is handled before the mediaPermissionPending_ guard in the
inbound event handler: that guard drops stale messages of a settled permission
request, and device selection happens long after, with no request pending.

Temporary instrumentation to track the data flow while investigating why a controller in a car still pauses after it obtained a microphone stream. Logs the microphoneRequested send, the stream-open event the platform uses as its second anchor, the reported devices and the inbound device selection.
