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 00:1b.0 Audio device: Intel Corporation 6 Series Chipset Family High Definition Audio Controller (rev 05) Subsystem: ASUSTeK Computer Inc.

Any advice greatly appreciated.
I had the same problem. I solved it by running the following command
Inside a terminal window (Ctrl+Alt+T to open one).
