Audio capture in Firefox doesn't work

That was a tough one.
Implemented in d1d3e15...86f0841. Most of it probably is not necessary. And eventually the main obstacles were capture buffer overruns and overrun recovery code. Buffers are now at least four times as big as period sizes, and there is additional state recovery code.

Should work in v0.1.10 now.

@i-rinat Are you sure, that it really works? I have tried http://appear.in/ and http://meet.jit.si/ and both seem to have issues with recognizing audio inputs ("the microphone couldn't be found"). Shouldn't apulse tell browser some additional metadata, perhaps at least fake one?

I didn't actually tried to make a call through meet.jit.si, but microphone selection in Firefox looks fine:

It does that, here:

apulse/src/apulse-context.c

Line 263 in 86f0841

pai_fill_default_source_info(void)

Are you sure you are using apulse v0.1.10?

[i-rinat]

For some reason, neither meet.jit.si nor appear.in work in Firefox 53 on my machine. It doesn't seem to be related to apulse, as it has the same behavior even with PulseAudio.

On latest master (bcd55c8), I can use my mic just fine with Jitsi Meet, so this seems to be fixed.

Doesn't work on 0.1.13 for me in firefox-82.0.
https://test.webrtc.org/ tells me that

Audio capture
[ OK ] Audio track created using device=default
[ FAILED ] No active input channels detected. Microphone is most likely muted or broken, please check if muted in the sound settings or physically on the device. Then rerun the test.

It works fine in ALSA with software like Mumble tho.
