Re: [webrtc-extensions] Enabling opus stereo audio without SDP munging (stereo=1) (#63)

> @fippo noted that Firefox already sets stereo=1, which I've confirmed.

Haha, well there we go.

And here's a modified version of @jan-ivar's fiddle that logs the channelCount:
When I run it on my MacBook Pro I get channelCount:1 in both Chrome and Firefox. I checked Safari too, but channelCount is undefined there. In any case, thee SDP is the same as Chromium.

@guidou Do you know what Chromium's default for channelCount is? I would assume that a normal microphone is 1 but I don't know what happens if you have some multichannel sound recording equipment.

I think if we write a PR to make stereo=1 the default we just need to make sure that Chromium does up and downsampling correctly, i.e. we don't want stereo=1 to cause us to encode stereo if our MediaStreamTrack has a mono source. @perahgren What would happen today?
