I am getting sound from other applications I've tried (Chromium, VLC, Videos), but nothing from Firefox.

Everything looks like it should be working. In sound settings, Firefox is turned up to 100% and when I play something, the output device even lights up like it thinks that sound is coming out, but it isn't.

  • In my case, Firefox sound was muted in the Volume Control Manager. I was complaining and suffering since weeks :( – smonff Jul 17 '20 at 9:21

    I never did figure out the problem. IIRC, after a restart the problem went away and I haven't had it again. – Jeremy Jul 18 '20 at 18:43

Install pavucontrol:

sudo apt install pavucontrol

Select required sound device on the Playback tab if a few are installed:

Try different output channels on Output Devices tab if a few are available:

In Gnome (Debian buster) I had the same problem on Youtube with Firefox only (system sound/Chrome and any other application was ok): I had to play a Youtube video, while playing the video I checked the Gnome sound system parameters and select "Applications" tab (you should see Firefox in the list), there the sound was only set to about 10%, I have no idea why...I suspect that this sound parameter has been changed by using VLC volume control...

  • OP says Firefox was turned up to 100%... – Zanna Apr 23 at 13:09
  • @Zanna is Firefox greyed out? It is nearly unperceptible. In my case it was. If it's your case, just click on it and it will reactivate. – stefano Jun 7 at 5:50
