I couldn’t get my sound to work. Here is what I went through.
This command will help you figure out what is installed:
skp@peanut:~$ lspci -v | grep -i audio
00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev a2)
This command can also help identify what is installed:
skp@peanut:~$ asoundconf list
Names of available sound cards:
NVidia
This command will also give you some clues:
skp@peanut:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 0/1
Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 1: ALC883 Digital [ALC883 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
My problem was that this command said there were no sound devices. I found I need to make the following changes.
I added these lines to the /etc/modprobe.d/options file:
# from: http://ubuntuforums.org/showthread.php?p=6313016
options snd-hda-intel model=3stack
I added these lines to the /etc/modules:
# from: http://ubuntuforums.org/showthread.php?p=6313016
snd-hwdep
snd-hda-intel
Then, I rebooted, and the sound worked!
