[hardy][alsa] controls out of place and volume control not working for HDA-intel + CMI9881 (solution included)

[thom]

Binary package hint: alsa-base

Hi there,

Problem:
Mislabeled and missing controls on mixers for HDA-intel with CMI9880 soundchipsets.

Caused by:
Missing model setting in alsa-base

Solution:
echo options snd-hda-intel model=full_dig >>/etc/modprobe.d/alsa-base

for other models see:
      http://wiki.sabayonlinux.org/index.php?title=HOWTO:_Resolve_Problems_with_HDA-Intel_Sound_Cards

Problem:
Volume controls don't work

Caused by:
Empty ~/.asoundrc

Solution:
copy attached .asoundrc file in ~

this should/could fix the following bugs:

Just testing on an Acer Travelmate 6292 with Ubuntu 8.10 Alpha 1, fully updated. It plays some sound but you can hardly hear it, even with maximum system volume.

cat /proc/asound/cards says:

+ 0 [Intel ]: HDA-Intel - HDA Intel
                      HDA Intel at 0xf0500000 irq 22
 1 [pcsp ]: PC-Speaker - pcsp
                      Internal PC-Speaker at port 0x61

head -n 1 /proc/asound/card0/codec* says

==> /proc/asound/card0/codec#0 <==
Codec: Realtek ALC268

==> /proc/asound/card0/codec#1 <==
Codec: LSI ID 1040

I tested with Ubuntu 8.04 before, and volume was a little better there.

Please execute the alsa-info.sh script referenced from https://wiki.ubuntu.com/DebuggingSoundProblems and attach the URL here.

The attached asoundrc is pretty useless, as it doesn't change anything from default.

This seems fixed for Ubuntu 8.10 (as of today) for an Acer Travelmate 6292.

Hi Daniel,

script output: http://www.alsa-project.org/db/?f=56776c28dd1432cf7562c0419bcccef89b319c24

sorry, I have been away for a while, switched to Intrepid in the meantime.
Still the same issue though so nothing has changed actually.
I still need the line: snd-hda-intel model=full_dig
in alsa-base to let it work correctly.

Yes, the asoundrc is default and therefor theoretically pretty useless indeed, strangely enough it didn't work without it which caused me a kind of "WTF?!?" reaction, I was baffeled ! :-)
In intrepid this is no longer needed btw.

Thanks for your reaction btw, and thank you for your help. I really do appreciate it.
