1869526 - In cubeb-coreaudio-rs only set up an VoiceProcessingIO AudioUnit when VOICE is preferred for the input stream

Status: RESOLVED FIXED

(Core :: Audio/Video: cubeb, task, P2)

Description

[Andreas Pehrson [:pehrsons]]

The VoiceProcessingIO AudioUnit forces both input and output to MONO, regardless of the capabilities of the devices involved. Not having the VoiceProcessingIO AudioUnit makes us susceptible to bug 1670633 for some input/output device pairs.

As a tradeoff, only use VoiceProcessingIO when VOICE is set in the input stream prefs, i.e. for getUserMedia with any audio processing constraint enabled. When all audio processing constraints are false, gecko does not pass in the input stream pref VOICE.
