Hi,
I am having a sound issue with my Eee that only occurs when I run Linux. Windows is totally fine, but I wiped Windows a little while ago. The laptop will play sound perfectly fine from its speakers, but anything plugged into the headphone jack is bound with large amounts of static-like noise. I am running Arch with all updates, and I am using ALSA.
Here is the output from lspci -v:

Update: The issue was with hardware. After an RMA, ASUS has fixed it.

I had a problem with noice when PCM was at 100% in ubuntu. Could that be the problem?

This doesn't seem to be the issue, but thanks for your suggestion!
