Just for the record, since you use Firefox 31.3.0, I don't think this is it, because it depends on gst-plugins-meta, which pulls in all relevant gstreamer plug-ins depending on your USE flags. The problem I was referring to above is limited to Firefox 35.0.

From what you say, I agree with your assumption that playback itself works. Although, I vaguely recall that Firefox can play videos without sound if only the audio codec is unsupported (or maybe I'm thinking about playback without soundcard access, like when I have JACK running), so it could *potentially* still be a codec problem, despite what I wrote above. You should be able to verify that with the debug console that I already mentioned. Now as to why you don't here anything, I can only, at best, make educated guesses. Alas, I use pulseaudio, so I don't have any experience with Firefox with USE=-pulseaudio. My only ideas at the moment are: - Verify that sound in other applications works, if you haven't already. - Double-check the volume settings. - Verify that Firefox can actually access the soundcard (though this should not be a problem if you use the ALSA dmix plug-in, which is the default, I think). - In the event that it might be a codec problem after all, verify your USE flags (e.g., check for mp3, ogg, or whatever is failing). I don't think that there are any audio settings in Firefox itself, though I could be mistaken (I did look in about:config, but still couldn't find anything).
