I guess it happened at the last update. My sound suddenly stopped working. I tried to reinstall the sound devices:
apt-get remove --purge alsa-base pulseaudio
apt-get install alsa-base pulseaudio
sudo alsa force-reload
It didn't work, still no sound. I got the following output:

When I execute aplay -l I get the following output:
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 3: VT1708S Digital [VT1708S Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
It seems that one device is suddenly started twice and using the same resources. That's why one blocks the other one, I guess. What can I do?
[UPDATE]
First of all I was able to get it running again by the following commands:
killall pulseaudio; rm -r ~/.config/pulse/* ; rm -r ~/.pulse*
wait ten seconds, then run this:
pulseaudio -k
apt-get remove --purge alsa-base pulseaudio
apt-get install alsa-base pulseaudio
But after playing some minutes it stopped working again.
It worked when the output of aplay -l looks like this (see the subdevices):
**** List of PLAYBACK Hardware Devices ****
card 0: SB [HDA ATI SB], device 0: VT1708S Analog [VT1708S Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 3: VT1708S Digital [VT1708S Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
It obviously does not work when the subdevices are both 1/1. But why is this switching and how can I stop it?
[UPDATE]
I rebooted. It worked again after reboot but after some minutes playing it suddenly stopped working again. I can confirm, that it worked while one subdevice was 0/1, the other 1/1, and as it stopped working, both are 1/1?
[UPDATE]
I added the following line
options snd-hda-intel model=generic
to
/etc/modprobe.d/alsa-base.conf
...restarted and didn't have a crash for a while now. I hope this was the solution.
[UPDATE]
Didn't work. Subdevices changed again. No sound.
