Description:

After a new installation of Arch, when i tried to configure the sound device using alsaconf i get the following error:
No supported PnP or PCI card found.

This morning my system was up-to-date and the sound was working.. weird.. the last time i manage to get the sound working i was using kernel 2.6.33.4

it seems to be a kernel26-2.6.34 related issue from the moment that now i'm using kernel-lts and the sound card is detected like it normally should.

now i'm using

$ cat /etc/modprobe.d/sound.conf
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel

Same problem.

Bored to compile nvidia package everytime for kernel-lts because of the problem of alsa with kernel26.Thanks Tobias and Thomas if u solve this problem...

This issue went away for a while and came back some time ago... kernel26-2.6.38.2-1

Running alsaconf is not a test if audio is working, nor is it helping. In the past, alsaconf has even caused sound to not work when people used it. Ergo: you don't need it, so don't use it.

The lsmod output in the original report indicates that everything is fine, the audio modules are loaded as expected.

hmmm.But any idea to explain why alsa works with kernel26-lts but not with kernel26?

Since installing core/kernel26 bumping to kernel version 2.6.38 I haven't had any audio. lspci shows zero audio devices. This was working flawlessly until the update.

Attempted to install kernel26-lts with same results.

This is an entirely different problem, open a new bug report.

What is the status of this bug report? You don't use archlinux anymore ?
