I was trying to get IEC958/SPDIF optical out working on my ASUS P8P67PRO V3 motherboard running Natty and I seem to have wiped out a crucial part of my sound setup.

Here is the output from some relevant commands (I hope):

sudo aplay -l  
aplay: device_list:240: no soundcards found...

ls /cat/asound*
ls: cannot access /proc/asoun*: No such file or directory

lspci -v

are you using that standard natty kernel or a later version? –  fossfreedom Aug 19 '11 at 17:49

thanks @dave, unfortunately the first step assumes there are entries in /proc/asound which are missing for me... –  Jonathan Day Aug 19 '11 at 23:28

I had the same problem. I solved it by running the following command

sudo modprobe snd-hda-intel

Inside a terminal window (Ctrl+Alt+T to open one).

Upgraded from 12.04 to 12.10 with the dist upgrade tool. First there was no grub and repaired that with rescatux. Then there was no soundcard found. I have looked through page after page and tried many of the solutions, about three hours of work when the solution was so simple that I'm surprised it's not the number one search result for this problem. Here it is:

Install the header and image files for your kernel.

sudo apt-get install linux-headers-3.5.0-26-generic linux-image-3.5.0-26-generic

I hope this works for you too!
