PulseAudio or ALSA, I cannot tell which, randomly mutes itself for no reason. This is EXTREMELY frustrating. It happens typically when I am playing a game, but can also happen when playing a movie. I have tried muting my microphone when not using it; this does nothing. I have also tried googling for fixes, and have found nothing. Any suggestions?

Kill pulseaudio from terminal on login, then launch it again. Can you post the output from terminal when it mutes? By mutes, do you mean you can unmute it after with the key? Or it stops completely?– TimJun 14, 2014 at 19:24

If sounds stops randomly, this is certainly a pulseaudio problem: you can remove Pulseaudio and stay without it in the case you have only one sound device (internal sound card and no bluetooth or other ) . At least,removing it temporarily is a good test for your problem.
To remove it:
sudo apt-get purge pulseaudio
sudo apt-get install gnome-alsamixer
Reboot and set the volume with the Gnome Alsa mixer (in the multimedia menu), or alsamixer in a terminal.

Audio suddenly stopped, pulseaudio reinstall has not helped? (14.04)

This happened to me as well. I didn't really have to use terminal, but it usually depends on your audio source. You can go to audio mixer, click on configuration,an look at the audio source options. Try all of them and see which one works. What can also work is to set the audio source as fallback. Just press the check-mark next to the audio's name. Hope I helped :)
