Comment 158 for bug 318942

HP110, Ubuntu Netbook Remix here, 2.6.28-13-generic. No sound without headphones.

Arnaud's solution did not change my situation, I still got headphone sound, but nothing in speakers.

Mauricio's solution left me without sound even when using headphones. (Actually, if I plug the headphones half way in, I can hear sound, but when they are flush, I get nothing).

Did not find Import0 Mux, but checked all the other inputs and cranked all their volumes, still only get sound when headphone jack is partway in.
