Sound ceased to work after three and half months OK 11.10

try:

killall pulseaudio; rm -r ~/.pulse*

Wait a few seconds then try some sounds.

Tried that. "no such file or directory" Rather odd.

Hey Ian,
Please open terminal by pressing CTRL+ALT+T and copy and paste the following command
uname -a && sudo aplay -l && lspci -v | grep -A7 -i "audio"

this command will ask you for your password, type it in and press enter. Please note when you type your password in terminal you will not see it as you type, this is normal.

Please copy and paste the output of those commands here for review.

Now please run the following command found at this link under 11.10

Copy and paste that entire command into terminal and press enter, then reboot and test your sound please.

Please execute step 1 and step 2, then reboot and send us the full terminal output from step 3 and step 4 from this procedure:
