Matthew, the new assert in wasapi is being hit in the wild. Would you like to take a look? Maybe we need to abort if COM is not initialized.

This path shouldn't happen I think. This is an OfflineAudioContext it seems, but we're reaching out to hardware. The assert added simply reveals an existing problem. I'm taking this, thanks for the analysis and filing Calixte.

clearing the NI for kinetik, since the assert in cubeb did its job, but is merely a consequence of this bug.

Pushed by padenot@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/e2bae3610871 Don't rely on the MSG to determine the number of channels to use, pass it instead. r=karlt
