I have checked here :-

but that didn't shed any light. I also believe that I am running off the latest
alsa drivers ie Advanced Linux Sound Architecture Driver Version 1.0.13. Is that

Comment 3 Martin Stransky 2007-03-06 17:35:47 UTC
hm, it looks like a problem in drivers:

Intel ICH: probe of 0000:00:04.0 failed with error -12

The latest drivers are 1.0.14rc3, on my page are 1.0.14rc2.

Comment 4 Craig Lister 2007-03-06 21:44:11 UTC
I am up to date from the Fedora site?? How come I need to load extra drivers??
Where do I get them from if not from the Fedora updates??

Comment 5 Martin Stransky 2007-03-07 10:41:32 UTC
They are not in fedora updates.

Comment 6 Richard Steck 2007-03-07 21:51:51 UTC
Identical problem started here today after updating from FC5 to FC6.  Have 
sound with WinXP.

Problem also started on an FC6 system which went through normal updates today. 
Something killed all sound.  My Default PCM device,  STAC92xx Analog 

Comment 7 Craig Lister 2007-03-07 23:49:49 UTC
Do you have a link where I may get the latest drivers?

Comment 9 Richard Steck 2007-03-08 16:07:03 UTC
When I try to install , I am told
there is a missing dependency for

Please tell me where to get the latter.

Comment 10 Craig Lister 2007-03-09 01:33:08 UTC
I have the same problem :-

[root@cjlhpc Desktop]# rpm -Uhv

Comment 11 Craig Lister 2007-03-09 02:23:48 UTC
I think that I sort of have a work-around for this problem. If after boot I go
into the sound detection applet there are, on the sound test main tab,  two tabs
listed there, nVidia - CK804 AC'97 - snd-intel8x0 and PNPb006 - PNPb006 -
mpu401. No amount of sound testing here yields any result. If I then go to the
main System tab and hit 'Reload audio drivers' it says that they cannot be
reloaded and to re-boot.

If, however, I load KDE and try the same procedure, I still have no sound from
either device, BUT if I go the the main tab System and hit 'Reload audio
drivers' they reload and now I have sound ???

Comment 12 Martin Stransky 2007-03-22 10:54:21 UTC
Can you please try to add these lines to your /etc/modprobe.conf?

alias snd-card-2 cx88_alsa
options cx88_alsa index=2

They should move cx88_alsa to the third position and free a slot for snd-intel8x0.

Comment 13 Craig Lister 2007-03-22 11:27:38 UTC
Ok, my modprobe.conf now looks like this :-

alias eth0 skge
alias eth1 forcedeth
alias scsi_hostadapter sata_sil
alias scsi_hostadapter1 sata_nv
alias snd-card-0 snd-intel8x0
alias snd-card-2 cx88_alsa
options cx88_alsa index=2
options snd-card-0 index=0  
options snd-intel8x0 index=0  
remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-intel8x0
alias snd-card-1 snd-mpu401
options snd-card-1 index=1  
options snd-mpu401 index=1  
remove snd-mpu401 { /usr/sbin/alsactl store 1 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-mpu401

Comment 14 Martin Stransky 2007-03-22 11:31:10 UTC
So does it work fine? (after reboot)

Comment 15 Craig Lister 2007-03-22 11:46:17 UTC
Yes the sound is there but it takes about 5 mins for the desktop to come up???

Comment 16 Martin Stransky 2007-05-16 13:10:18 UTC
Hm, this change makes your boot so slow?
