Hello everybody,
I use FC3 + kernel 2.6.9-1.724_FC3smp ; the sound card is identified without problems and sound works fine.
I tried with kernel 2.6.10-1.737_FC3smp ; the auto detection of the sound card works and yields the same as with kernel 2.6.9-1.724_FC3smp. But sound does not work !
I have the same problem with kernel 2.6.10-1.741_FC3smp.
Does somebody have an idea or a suggestion ?
Also I never could listen an audio CD ; the CD is read and the tracks are listed correctly, but no sound.
Okay, what soundcard do you have? What modules were loaded with kernel 2.6.9-1.724_FC3smp? Did you check /etc/modprobe.conf?
apprich@elmstreet apprich $ grep snd /etc/modprobe.conf
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
My /etc/modprobe.conf is exactly the same:
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :
remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0

Did you check /var/log/messages for error messages?
The only error message I can see in /var/log/messages (and clear related to kernel 2.6.10-1.741 is the following:
Jan 17 07:24:23 dc4u kernel: PCI: Using ACPI for IRQ routing

I tried to restart the new kernel with the pci=routeirq argument, but it does not work better.
Hmmm, could you also try booting with
acpi=off
instead of
pci=routeirq
Did you try reconfiguring your soundcard using system-config-soundcard? With the old kernel does your soundcard still work? Could you compare the output from the old and the new kernel?
