Comment 18 for bug 94566

Ah, your sound control seems quite different than mine then. Here, the headphones and speakers channels are the same, known as "Master volume". So I can't adjust headphone volume independently of speakers volume. So you are saying is that you have an headphone channel which is non fonctionnal when playing with it (a "useless" volume control), right?

Have you already tried on feisty (or edgy) the previous fix with success on your laptop? (thge one with alsa 1.0.14) Because if you have a different codec than AD1986A, the patch won't fix anything...

cat /proc/asound/card0/codec#0 | grep Codec

should give you AD1986A...
