Comment 6 for bug 58751

So, more info: If you turn LFE all the way down, it works like expected. This all seems to be related to LFE (Bass channel). Apparently, its able to bypass the master volume, but PCM is not. so, my guess is, whatever audio backend we all are using routes LFE incorrectly. When mute is on, the sound is substantially different than with it off. I didn't discover LFE until recently, and I would like to have it work correctly. Incidentally, with LFE on, turning down master volume seems to have little effect, but turning the master down to zero effectively mutes it, even if you have LFE on.
