I have installed Nvidia graphic drivers for my Debian 8, but the installation contained a new sound driver, which has broken the sound on my PC. How can I uninstall the Nvidia one and restore the default Debian 8 sound drivers?

EDIT: My lsmod output:

  • Some more information might help here: /proc/asound/cards and devices, something like lsmod | grep snd,... It is possible, that you just need to select a different "default sound card" somewhere in your Desktop environment. Nov 7, 2015 at 13:05
  • Ok, added lsmod.

  • use | grep snd to filter the output. Prepend the output from cat /proc/asound/cards Nov 7, 2015 at 13:20

I have found the solution:

I needed to install the alsa-oss with apt-get install alsa-oss.

For being able to use my headset too, I needed to install the alsamixergui with apt-get install alsamixergui.

You can take a look at it's description on this site: https://wiki.debian.org/ALSA
