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…
