Hi

Since kernel 2.6.33 (and including 2.6.34-rc5-git10), sound output is
broken on my Intel D945GCLF2 mainboard, while it did work well on earlier
kernels up to and including 2.6.32.12.

Experimenting with different module parameters for snd-hda-intel don't seem
to be successful, neither enable_msi=0, different model= or probe_mask=
settings seem to have any effect.

Reverting just "ALSA: hda/realtek: quirk for D945GCLF2 mainboard" however
fixes my problem on 2.6.33 and 2.6.34-rc5-git10.

Revert "ALSA: hda/realtek: quirk for D945GCLF2 mainboard"

This reverts the following commit:
7aee67466536bbf8bb44a95712c848a61c5a0acd

As it doesn't seem to be universally valid for all mainboard revisions of
the D945GCLF2 and breaks snd-hda-intel/ snd-hda-codec-realtek on the Intel
Corporation "D945GCLF2" (LF94510J.86A.0229.2009.0729.0209) mainboard.

Could you give alsa-info.sh output (run with --no-upload option)?
I would revert in the worst case, but before that, I'd like to analyze
the real issue.


thanks,

Attached are alsa-info.sh and full, as far as the buffer allows, dmesg
outputs from:
- plain 2.6.34-rc6-git5, no sound:
+ alsa-info_plain-2.6.34-rc6-git5.log.gz
+ dmesg_plain-2.6.34-rc6-git5.log.gz
- 2.6.34-rc6-git5 with the proposed
"revert-ALSA_hda-realtek_quirk-for-D945GCLF2-mainboard" applied:
+ alsa-info_revert-ALSA_hda-realtek_quirk-for-D945GCLF2-mainboard.log.gz
+ dmesg_revert-ALSA_hda-realtek_quirk-for-D945GCLF2-mainboard.log.gz
the kernel config is config-2.6.34-rc6-sidux-amd64.gz in both cases.

Additionally I've tested a current OpenSuSE factory live CD
(openSUSE-KDE-LiveCD-x86_64-Build0589-Media.iso) daily with kernel
2.6.34-rc - sound not working:
+ alsa-info_openSUSE-KDE-LiveCD-x86_64-Build0589-Media.log.gz
+ dmesg_openSUSE-KDE-LiveCD-x86_64-Build0589-Media.log.gz
and a few days old Fedora rawhide nightly with exactly the same symptoms,
no logs attached.

Up to and including kernel 2.6.32 (tested since ~2.6.26) ALSA always worked
out-of-the-box, once I revert 7aee67466536bbf8bb44a95712c848a61c5a0acd
(ALSA: hda/realtek: quirk for D945GCLF2 mainboard) from 2.6.33(.3) or
2.6.34-rc6-git5, snd-hda-intel/ snd_hda_codec_realtek have managed to
initialize again in all my my tests so far. I'd be happy to test any
potential alternatives to that patch. Unfortunately I usually don't notice
graphics or audio regressions quickly, as that system is running quasi
headless/ speakerless most of the time, but I can test it any time of
course.

Could you try probe_mask=4 option without reverting?
I don't find any wrong verb with the quirk, so this looks more like a
problem in the slot probing.


thanks,

Takashi

Unfortunately I can't observe any improvement with probe_mask=4, logs
attached.
