Firefox 52 requires PulseAudio to play sound

[ahanson]

Firefox version 52 requires pulseaudio to play audio.

How to fix the issue:

Open a terminal and type: sudo apt-get -y install pulseaudio pavucontrol Then, check if your pulseaudio configuration directory is owned by your user. Type: ls -la ~/.config/ | grep pulse Your output should look something like this (where user is your username): drwx------ 2 user user 4096 Feb 4 2015 pulse If you see this: drwx------ 2 root root 4096 Feb 4 2015 pulse Then you need to type this: sudo chown -R user:user ~/.config/pulse and after that , sound should work in Firefox.

It's easy to add pulseaudio and set the correct permissions for the config directory. The problem is that I don't know if this will break something else.

Isn't Pulseaudio installed by default on Xubuntu? I have no problems with sound in firefox 56 on 17.10.

Dunno about Xubuntu, but it sometimes doesn't appear on Kubuntu 14.04. Other times, it's present, but the /home/user/.config/pulse/ directory is owned by root for some reason. Next year, we're moving to Linux Mint, so maybe this won't be an issue there.

Ugh, Mint…
