Firefox makes no sound
I asked this question 2 years ago. It's closed so I have to ask again. Firefox makes no sound. I have a YouTube video playing, for example, and I can see the video, but there's no sound. YouTube's unmuted, the volume is all the way up. If I download the video I can play it with mplayer and hear the sound. I can watch a DVD with xine and hear the sound. I can play an audio file at the same time and hear the sound. I've encountered some videos I can't download so I can't hear them - I have to go to the library to use their computers.
I see 'failed to init cubeb... AudioStream.cpp line 387' and 'OnMediaSinkAudioError... MediaDecoderStateMachine.cpp, line 3755'
if those mean anything.
Chosen solution
pulseaudio is running. Removing '--disallow-module-loading ' solves my problem. This security measure is in Slackware's rc.pulseaudio. I'll tell them about it.

I tried all of this BEFORE I asked here. I've had this problem for more than 2 years.
Do you have PulseAudio installed?
I have tried both with and without pulseaudio. When I have pulseaudio running I have run pavucontrol, turned the volume all the way up, made sure speakers were unmuted.

Hmmmm... I was running as root when this fix worked; when I run as myself it doesn't. (Yes I tried it as root before) so I have a permissions problem too; would anyone know what? I've looked at lsof's output but that hasn't helped.
