[SOLVED] no soundcard: hda-intel (MCP55)

I think I have things set up correctly, but Arch will not find my sound card.

The sound "card" is integrated into an nForce550 Gigabyte M55S-S3 motherboard:

lspci|grep Audio
00:06.1 Audio device: nVidia Corporation MCP55 High Definition Audio (rev a2)

Part of dmesg afther booting:

[root@. karel]# dmesg | grep intel
 [<f8f2bdc0>] azx_interrupt+0x0/0xf0 [snd_hda_intel]
 [<f8f2b192>] azx_acquire_irq+0x32/0x80 [snd_hda_intel]
 [<f8f2c15b>] azx_probe+0x17b/0x810 [snd_hda_intel]
hda-intel: unable to grab IRQ 15, disabling device

Modules are loaded I think:

karel@. lsmod | grep snd
snd_seq_oss            29440  0
snd_seq_midi_event      6528  1 snd_seq_oss
snd_seq                47056  4 snd_seq_oss,snd_seq_midi_event
snd_seq_device          6796  2 snd_seq_oss,snd_seq
snd_pcm_oss            38944  0
snd_mixer_oss          14464  1 snd_pcm_oss
snd_hda_intel          15768  0
snd_hda_codec         156800  1 snd_hda_intel
snd_pcm                68612  3 snd_pcm_oss,snd_hda_intel,snd_hda_codec
snd_timer              18948  2 snd_seq,snd_pcm
snd                    44004  9 snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd               _mixer_oss,snd_hda_intel,snd_hda_codec,snd_pcm,snd_timer
soundcore               6624  1 snd
snd_page_alloc          7816  2 snd_hda_intel,snd_pcm

But there's nothing in /dev:

ls /dev/snd
seq  timer

I *think* the problem is with hda-intel: unable to grab IRQ 15, disabling device, but don't know what I could do with it.
There's not much about it on Google, only a mail about a patch to alsa(?) if I get it right.

I have tried to boot with pci=biosirq, pci=routeirq, without any success.

Please help :-)

Not sure that it will help, but you could try the following boot parameter:

pci=assign-busses

You might try fiddling with BIOS settings.

Sorry, I read only now the google link you posted. What the patch you refer to does can be done with the following boot parameter:

pci=nomsi

That's what helped!

I have disabled IDE, paralell and serial port in BIOS, and the sound card is detected, Amarok is already bangin'

I have tried the pci= kernel option, but they had no effect.

Thanks for the ideas and help!

(ps: can i change the topic title to [solved] somehow?)

Yes, you can edit your first post and you should be prompted to change also the title.
