I recently switched my main workstation running CentOS 7 from KDE to MATE. Migration went well, but now I have a couple issues. First things first.

I have no sound in the Firefox browser. Applications like Audacious, VLC or MPlayer have sound, but Firefox is mute.

Any idea how I can fix that?

I'll answer that myself, since I just found the culprit. I installed pulseaudio and pavucontrol, which were missing from the package group. Now everything works fine.

Cheers,
