Hi,

I'm currently running a 2.6.19 kernel and 2 times out of 3 the sound driver fails to load hence probing me a no sound device available in KDE.

Once I reload the driver this output goes into the dmesg:
usbcore: deregistering interface driver snd-usb-audio
ACPI: PCI Interrupt Link [APCJ] enabled at IRQ 22
ACPI: PCI Interrupt 0000:00:04.0[A] -> Link [APCJ] -> GSI 22 (level, low) -> IRQ 22
PCI: Setting latency timer of device 0000:00:04.0 to 64
intel8x0_measure_ac97_clock: measured 51418 usecs
intel8x0: clocking to 46862

I've attached the dmesg and the lspci -vvv.

Could the snd-usb-audio interfere with the on-board sound driver?

Yes, if you set index=0 module option to snd-intel8x0 driver and
nothing to snd-usb-audio, they may conflict according to the order of
loaded modules.  Pass index=1 (or index=-2) to snd-usb-audio module
option to make the index order consistent.

Now there is a bug opened up at redhat:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=229227

I've ran into this info:
http://www.lavrsen.dk/twiki/bin/view/PWC/FrequentlyAskedQuestionsPWC#modprobe_fails_with_FATAL_Error
and did removed the index=X line associated with the pwc driver.  This still create a problem from time to time.

Seems like the index=X option is broken in the alsa driver (or maybie deprecated, remove, buggy, duno?). There is another way to fix the problem by using a /etc/asound.conf file (see http://alsa.opensrc.org/FAQ026) and removing the index=X entries from your mdoprobe.conf file

Maybie the Fedora team should use the asound.conf configuration instead?

thnx!

This doesn't work for apps that use the deprecated /dev/dsp API.

Of course, a modern distro should be trying to purge these anyway...
