To add a new angle to an old problem:

I'm running Maverick on an Asus P50IJ, and my headphones are causing me a headache (figuratively).

Originally, sound came from internal speakers and headphones simultaneously. After fiddling around with tips from different forums, I lost sound altogether, then only when headphones were plugged in. I've now got internal speakers back to normal, but headphones are dead. Mic seems to work though.

My soundcard seems to be VIA VT1708S (?)

Does anyone have an idea?

Could it be a hardware problem?
Old drivers?
Thanks for any help!

BTW: I'm not that new to ubuntu, just obtuse, so please go easy on the techie talk - thankyouthankyou!
