I have an Asus EeePC 1018p and I'm having trouble debugging an audio problem in Lucid. The internal microphone does not work, nor does the headphone jack or external mic input. I've tried fiddling with alsamixer, pavucontrol (some fixes involve setting turning down the left or right capture channels), etc., but haven't had any success.

It seems that many people with EeePCs (other models) have fixed the problems with what I mentioned above, but it's no use for me. I've also booted into UNR to see if the modified kernel that it ships with fixes any problems, but nothing changed.

Any ideas? I don't even know which logs to look in to find the issue.

Here is some information on my system if it helps.
