Looking at the screenshot the audio appears to work at the right frequency, but the amplitude is too low for some reason.

Paul, what do you think this could be? I'm stumped.

It's just after audio-only gUM that we forward the audio track through a media element's mozCaptureStream() (which is just a regular MediaInputPort locked to that one track) and the amplitude of the analysed TEST_AUDIO_FREQ appears too low.

I was going to suggest MediaEngineDefaultAudio underruns but this is so early in the test and I think it buffers up some extra data in the beginning so it shouldn't be that.

How low is it? Could it be because of the windowing of the AnalyserNode ?

Currently I'm looking at multiple tests failing in the same way, though this is the only one where we have some kind of proof of what's going on.

I think this is because of MediaEngineDefaultAudio being push based, but let's see.
