Hi.
On rebooting after running pacman -Syu yesterday my sound card devices aren't being created. Here's what was upgraded:
[03/12/07 13:08] upgraded ati-fglrx-utils (8.34.8-2 -> 8.34.8-3)
[03/12/07 13:08] upgraded gstreamer0.10 (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded gstreamer0.10-base (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded gstreamer0.10-alsa (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded gstreamer0.10-cdparanoia (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded gstreamer0.10-gnomevfs (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded gstreamer0.10-ogg (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded gstreamer0.10-vorbis (0.10.11-1 -> 0.10.12-1)
[03/12/07 13:08] upgraded kernel26 (2.6.20.1-2 -> 2.6.20.2-1)
[03/12/07 13:09] upgraded libgksu (2.0.3-1 -> 2.0.4-1)
[03/12/07 13:09] upgraded libmysqlclient (5.0.27-1 -> 5.0.37-1)
[03/12/07 13:09] upgraded libtasn1 (0.3.8-1 -> 0.3.9-1)
[03/12/07 13:09] upgraded soundconverter (0.9.3-1 -> 0.9.4-1)Presumably the kernel upgrade is the problem, since gstreamer isn't that fundamental.
The modules are loaded:

Thanks.

Sorry for the sheer mass of output here, but I'm not sure what's relevant. Some further info:
lspci shows:

hda-intel: no codecs initialized

Any suggestions would be greatly appreciated.

There's been a change ("hda-intel - Don't try to probe invalid codecs") that apparently causes your problem, but don't ask me for solutions ;-)

Thanks for the info. This looks a likely cause, but I've no idea what to do about it. I wonder does this just mean the drivers won't work with my soundcard for the moment? Perhaps I'll have to roll back to kernel 2.6.20.1.
If anyone knows how to fix this problem (or even how to interpret what exactly has been changed), I'd appreciate your help.

I have the same problem so i'll try to look up on the problem and see if i can find a solution.. if i do i'll post it.

burgler09, Have you made any progress? I use the snd_hda_intel module and with the latest kernel I just cannot get sound to work even though the modules are loaded. I finally reverted to the older kernel and everything works. Would like to find a proper solution to the problem though.

I just tried 2.6.20.3 and the problem persists. I'm having to stick with 2.6.20.1 for the moment, but obviously I'll have to upgrade the kernel eventually. Keep me posted if anyone fixes this.

Fixed in the latest kernel. See http://bugs.archlinux.org/task/6617
