Re: [mediacapture-main] what is the default channelCount (#775)

> There is apparently no consensus for channelCount yet. We should acknowledge this and seek for consensus.

To clarify, no consensus is needed today, as it is up to user agents. This ensures defaults can keep up with changing times.

But the OP question is useful, whether it leads to more spec language or not, because it's revealing implementer bugs.

To answer: Firefox defaults to the max a microphone can do, capped at 2. But we've found bugs ([1](https://bugzil.la/1696508), [2](https://bugzil.la/1696519)). This represents our desire to promote stereo for users who have stereo (both in audio apps and web conference calls).

But regardless of what the default is, we need to ensure all browsers are able to send and receive stereo, and that they're not wasting bandwidth upsampling mono to stereo. We should ensure we have WPT tests for this.
