Summary:                    intel8x0 driver is not able to find sound card
Description: 
Hi folks, 

  I've been using the intel8x0 alsa driver since kernel 2.6 without any
problems upto kernel 2.6.5 (compile from vanilla). However, since 2.6.6
and 2.6.7 came out I'm not able to listen to any audio as the driver does
not seem to recognice my card. I've made NO changes to the configuration
files of the kernel and to any other setup. Simple start 2.6.5 alsa works,
reboot with 2.6.6/7 and sound is not working.

 The modules are loaded (same modules). "alsaconf" (1.0.5) reports the
right card and loads it but for instance "alsactl restore" fails...

Hi again,

  First of all, thanks tiwai for your time helping me find this problem. 

I've check all this again and it actually seems to be two mixed bugs.
First of all I've check my windows partition and I've seen that modem and
sound card also shared the same IRQ so as you said that shouldn't be the
problem :-(

Anyways, I've tried all possible configurations in the bios (enabling
modem, infrared, parallel port, etc.) in order to check what was happening
and it seems the parallel port is causing the trouble:

- All enabled: Soundcard is *not* detected (output from
/proc/asound/cards) shows no soundcard 

- Parallel port disabled: Soundcard is detected only if (here comes what
looks the second bug) snd_intel8x0 is loaded *before* snd_intel8x0m.
Otherwise no sound.

So now I can decide between listening to music or using the printer :-) 

What do you think it may be the problem?

There was a problem regarding the probing of chips between
intel8x0 modem and audio drivers.  I fixed it yesterday on CVS.

Please try CVS version or wait for 1.0.6-rc release.
