What to do if sound goes to dummy output

Question

I sometimes find that the sound from my Linux G505s running 64bit Linux Mint 15 sometimes goes to Dummy Output as the output device.

What should I do when this happens(short of restarting my system)?

Solution 1

Not sure if you are still facing this problem. If you do try this. It worked for me:

pulseaudio -k

Solution 2

My solution was to:

cd /dev/snd; sudo chmod a+rw *; pulseaudio -k

I noticed that the neither gnome sound setup or alsamixer was picking up the device as a normal user, but alsamixer was picking up the device as root. All good now.

This worked for me too, using RHEL 7.5

Also worked for me on CentOS Stream 8, although I also had to do pulseaudio --start as I had disabled the auto start of pulseaudio.
