Arch Linux

I'm using the current kernel26 2.6.20.3-2, and snd_hda_intel works properly without any extra configuration (except in modprobe.conf the "options snd-hda-intel model=uniwill-m31", which should not have any effect on the module loading itself).

Georg

Tried almost all the options and still even though the module is loaded my soundcard is not detected. Reverting to the older kernel.

Same here with the current kernel26 2.6.20.3-2, on an Asus P5B Deluxe: module loads, but it doesn't seem to find any codec.

Found in dmesg when loading snd-hda-intel module:
hda-intel: no codecs found!

ok you guys, have entries in /etc/modprobe.conf am i right?
you used alsaconf for sound configuration right?

please remove the alsa entries from /etc/modprobe.conf.
you could also try to manually load your modules in rc.conf that udev does not mess up the module loading.

I have no entries in /etc/modprobe.conf and I never used alsaconf.
The soundcard worked out of the box with prior kernel26 versions.

Meanwhile, alsaconf detects the soundcard correctly, but I still have the same error in the dmesg.

Btw, same behaviour when the module is manually loaded in rc.conf:

:: Restoring ALSA Levels [BUSY]
/usr/sbin/alsactl: load_state:1327: No soundcards found...
[FAIL]
Clearing /etc/asound.state didn't help.

It doesn't seem like a specific problem with 2.6.20.3 as a quick browse on lkml doesn't show any bug reports of similar problems.

does manual loading of modules help?
try to load your needed modules in rc.conf and then recheck, it could be that udev loads the modules in wrong order.

what does hwdetect --show-modules give you?
pacman -S hwdetect

Manual loading doesn't help.

Can you point me to an earlier version of this package (for example kernel26 2.6.20.3-1), so I can test if I can reproduce the problem with it ?

in which order did you load the modules?

I used "modprobe snd_pcm" to load the generic alsa subsystem and then:
insmod snd-hda-codec.ko
insmod snd-hda-intel.ko

snd-hda-codec is always loaded before snd-hda-intel.

OK.
I missed this post on the archlinux forums on my first search: http://bbs.archlinux.org/viewtopic.php?pid=235674
I think the issue discussed here is exactly the same.
I'll try to rebuild the kernel26 package with this patch reverted:
http://lkml.org/lkml/2007/2/26/323

new kernel-2.6.20-3 should fix your issue, please report success.

the same issue with kernel26beyond and kernel26ck

works fine for me 2.6.20.3-3 thanks

Thank you very much tpowa. Works like a dream.

Argg... 2.6.20.3-3 doesn't work for me

A better patch was committed upstream:
http://article.gmane.org/gmane.linux.alsa.devel/45881

#define AZX_MAX_CODECS 4 corrects the behaviour of ATI-based HDA soundcards.

Meanwhile, mine is an ADI AD1988B that should not be affected. I posted a bug upstream as I can reproduce it with a vanilla kernel:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2976

its in .4 kernel that i'll commit right now
