[GUTSY] no audio in kernel 2.6.22-10

[sk0rp10]

No audio sounds out after upgrading to kernel 2.6.22-10

HDA Intel modules are correctly loaded for my card , Sigmatel chip, and no error is given in dmesg log.

Same problem on my Samsung X60p after installing 2.6.22-10.

For me the solution to this whole problem was to compile ALSA from the current snapshot source.
Namely:
alsa-driver-hg20070823
alsa-lib-hg20070823
alsa-utils-hg20070816
I just downloaded these three from
ftp://ftp.suse.com/pub/projects/alsa/snapshot/
compiled and installed the driver with
# ./configure --with-cards=hda-intel,usb-audio
# make install
and the other two with (first lib, then utils)
# ./configure
# make install
rebooted and all was good...
So this solved:
- sound output was very low, only after cranking up all sliders I was able to hear that there actually was sound...
- missing mixer controls, only three were left..
- no sound at all after suspend-resume without reloading snd-hda-intel
But still the internal mic is not working and the internal speakers don't shut up when I plug in a headphone!

Good luck to the rest of you

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
