I just installed Ubuntu 16.04 on a new computer. The sound worked fine for all users right after the installation but suddenly, the sound indicator was set to mute and I was unable to adjust the sound (the sound still plays though!!).

If I login as a different user (or even to guest session), the sound and sound indicator both work flawlessly. I tried to reinstall ALSA and pulseaudio but nothing changed. The weirdest part is that sound comes out of the speakers.

I don't think its a hardware detection failure because sound is coming out of the speakers, I have no idea what to try next - thanks in advance for the advice!

I had similar problem. Fixed it by killing pulseaudio and deleting its config folder:

killall pulseaudio && mv ~/.config/pulse/ /tmp/deleted_pulse_config

Thanks. The problem was already answered by this question:

I had to change permission for my home directory:

sudo chown -R <username> /home/<username>
