[Bug 77180] Sound card occasionally not found

[DavorCubranic]

Public bug reported:

Every so often, when I boot up into Ubuntu (Dapper, 32-bit Intel), the
sound card is not found. Other times, it works just fine. I never run
into this problem if I boot the same machine into Windows. The sound
card is a Realtek ALC880 (HD sound) integrated with the motherboard. The
motherboard is ATI's Xpress200 in a Shuttle ST20G5 (AMD64).

When the card is not found, I get the following error messages in the
terminal window:

ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'
ALSA lib conf.c:3493:(_snd_config_evaluate) function snd_func_card_driver returned error: No such device

Dmesg output shows the following two lines:
[   40.994319] hda-intel: unable to grab IRQ 7
[   40.994332] HDA Intel: probe of 0000:00:1d.0 failed with error -16

I will attach the full dmesg and lspci output separately.

** Affects: linux-source-2.6.15 (Ubuntu)
     Importance: Undecided
         Status: Confirmed
