Solved - no sound with kernel 3.2.4
maybe this might interest you. After updating to kernel 3.2 I got no sound. I
could see, that it was playing, but did not hear anything. As I read of others
with the same problem, here is the solution:
The new kernel module added two new regulators "speakers" and "headphones",
and they are both set to "0" by default!
Additionally kmix and some other GUI might not show them as well as alsamixer,
but just start "alsamixer -c0" and all sliders appear. Now you can set them as
you want, and now you can hear sound playing again.
I hope, this hint might help some others.
A great "thank you!" in this matter to Jonathan Nieder and Takashi Iwai, ho
helped me, to find the solution!
Happy hacking and best regards
