RHEL 4 2.6.9-42.0.8.EL kernel breaks sound for me... (again!)

[John_Hull at Dell.com]

Try removing all of that info below from the hwconf file, and then run
`kudzu` again on the command line. Verify that kudzu picked up
snd-hda-intel instead of snd-azx. Alternatively, you could replace
"snd-azx" with "snd-hda-intel" in that file, but I've had more success
with the first method.

Indeed there is:


class: AUDIO
bus: PCI
detached: 0
driver: snd-azx
desc: "Intel Corporation 82801G (ICH7 Family) High Definition Audio
Controller"
vendorId: 8086
deviceId: 27d8
subVendorId: 1028
subDeviceId: 01a8
pciType: 1
pcidom:    0
pcibus:  0
pcidev: 1b pcifn:  0

Anything to be done about that?

	Can you look at your /etc/sysconfig/hwconf file, and see if
there are any references to snd-azx?

	Any other suggestions John?  I'm still not getting consistent
sound.  I just rebooted into the new 2.6.9-42.0.10.ELsmp kernel and no
sound.  lsmod shows snd_azx is loaded.  How can I prevent it from
loading as you recommend?  (And why is it loading if it's the wrong
module?)
	
	Thanks.

		alias usb-controller1 uhci-hcd
		  
		Anywhere else I should be looking?  Also, just reverting
back to the .3.EL kernel gets the sound back, so that doesn't seem to me
to be a modprobe issue.  Thanks.

			You need to make sure that the snd_azx module
doesn't get loaded, as it conflicts with snd-hda-intel. Check to verify
that there are no references to snd-azx in the /etc/modprobe.conf file,
and if there are, change them to snd-hda-intel

:-).  I have a

patches.  If I revert to

2.6.9-42.0.8.EL (SMP or

snd" on .8.EL kernel, I
			get the following errors:
			
			snd_azx: disagrees about version of symbol

			Suggestions?
