2.6.16-rcX - no more sound with ALSA snd-hda-intel / Sigmatel

2.6.16-rcX - no more sound with ALSA snd-hda-intel / Sigmatel

[Marcus Hartig]

Hello!

Since the 2.6.16.rcX kernel versions I have no more sound with the ALSA 
snd-hda-intel driver. All modules load without errors, all  channels are 
unmuted, no errors in any log, but sound is death! :(

With kernel 2.6.15.6 (ALSA 1.0.10rc3) the sound is working, only that 
the headphones output is not doing any noise and then the internal 
speakers are not muted. With mplayer and ALSA sound output the CPU load 
goes very high and it stutters, with OSS output in mplayer OSS device 
not more.

This is an new DELL Inspiron 9400 Dual Core notebook with Sigmatel STAC 
92XX C-Major HD Audio.

lspci:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High 
Definition Audio Controller (rev 01) Subsystem: Dell Unknown device 01cd

Module options:
snd_hda_intel position_fix=1 index=0

What has changed since 2.6.15.X?


Greetings,
Marcus

Thanks, Adrian! Tried the patch on 2.6.16-rc6-git9, but only headphone 
output is working, now. Microphone not tested, alsamixer/gnome-mixer all 
channels are ok. But internal speakers are quiet, when nothing is to the 
jack connected, is it ok so as a quirk? ;-)

Marcus
