You probably are not on 17063 insider either ?

I am not but I know a lot of people with sound issues in Firefox. The problem started when Multiprocess was introduced. The people with the problem that I come in contact with are using Sandboxie. There is a conflict between Sandboxie and Multiprocess, that generates no sound in Firefox when running sandboxed (affects some users, not all). In your case, you are not using Sandboxie, but something else in your PC might be conflicting with Multiprocess that causes the sound in Firefox not to work. Perhaps something in the insider build is conflicting.

I am just trying to help Mike. Takes a couple of minutes to try the workarounds. If they work for you, you ll see the difference immediately.

Firefox 56/57 sound not working when sandboxed - Sandboxie Support

Bo, think this is another thing...

look here on reddit thread before Christmas

Very plausible. Workaround would be to change cubeb_wasapi.cpp - DXR
as follows

hr = stm->audio_stream_volume->SetAllVolumes(channels, volumes);
if (hr != S_OK) {
LOG("could not set the channels volume: %lx", hr);
return CUBEB_ERROR;
}

to

hr = stm->audio_stream_volume->SetAllVolumes(channels, volumes);
if (FAILED(hr)) {
LOG("could not set the channels volume: %lx", hr);
return CUBEB_ERROR;
}
