I came into an Abit AX8 motherboard and single core AMD Athlon 64 FX. I
did a quick install of CentOS 5.0 on it to make sure everything worked
and then returned the hard disk and case to the original owner. After
getting a new case and hard disk, I downloaded the CentOS 5.1 cd images
and installed. For some reason the motherboard's on board sound no
longer works (worked with CentOS 5.0). dmesg gives me:
ACPI: PCI Interrupt Link [ALKC] enabled at IRQ 22
ACPI: PCI Interrupt 0000:00:11.5[C] -> Link [ALKC] -> GSI 22 (level,
low) -> IRQ 90

ACPI: PCI interrupt for device 0000:00:11.5 disabled
VIA 82xx Audio: probe of 0000:00:11.5 failed with error -5
and I get the same result if I rmmod/modprobe the kernel sound module
(snd-via82xx).
lspci -vv gives me:

and my modprobe.conf (generated by kudzu) looks like:
alias eth0 r8169
alias scsi_hostadapter sata_via
alias snd-card-0 snd-via82xx
options snd-card-0 index=0
options snd-via82xx index=0
remove snd-via82xx { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-via82xx
I can always stick a spare sound card in the remaining PCI slot but the
sound card used to work with CentOS 5.0. It seems kind of silly that it
doesn't work now. I've Googled for some different parts of the dmesg
output but haven't found anything helpful. Same with error messages
from aplay, amixer, etc. Any suggestions would be appreciated.
Thanks,
Dave
