No sound after some time

[dohseven]

Since a few weeks the sound is suddenly stopping on my laptop after some time. This can happen when I play music with Spotify, talk with Skype or play with Steam. The only way to get the sound back is to restart the computer.

I tried to follow the sound troubleshooting procedure (https://help.ubuntu.com/community/SoundTroubleshootingProcedure) but it didn't solved my issue.

Attached are the information generated by the also-info script and the pulseaudio log taken while the issue occurred.

Any news on this bug? It's quite annoying to lose all sound...

The sound comes back after suspending the machine with `sudo pm-suspend`.

Only reloading alsa with `sudo alsa force-reload` or restarting pulseaudio with `pulseaudio -k && pulseaudio --start` doesn't work.

Updated to 17.04, issue is still there. I think it comes from alsa driver instead of pulseaudio.
