Description
When webrtc is enabled, other applications (meet, desktop applications, etc.) as well as viewer media and other sounds got quieter due to the Windows "audio ducking" feature which reduces volume when you use a communication audio device.
We move webrtc to default to the Media audio device, which doesn't do this.
Issue Link: https://github.com/secondlife/viewer-private/issues/666
Test Guidance
Bring up a viewer in an area with media and voice https://maps.secondlife.com/secondlife/Hanley/102/75/29
disable voice
listen to media
enable voice
expect media volume doesn't reduce
Bring up google meet
Validate meet voice level doesn't change when toggling viewer voice on or off
Bring up windows media player with an mp3
Validate playing media doesn't duck when toggling viewer voice on and off
