problems with redhat 8.0, sound, and intel 845 chipset



hi. i recently upgraded my old computer to a nice new Intel D845GEBV2
motherboard, with everything integrated. turns out this wasn't such a 
good idea because the linux driver for the video section is very buggy,
so i ended up buying a video card. no great worries.

my problem now is the sound: i get no sound out of the system. 
if i try to control sound (e.g. with the gnome-volume-control) i get:

	I was not able to open your audio device.
	Please check that you have permissions to open /dev/mixer
	and make sure that you have sound support compiled into your
	kernel

here are my mixer permissions:

	$ ls -l /dev/mixer
	crw-rw-rw-    1 michael  root      14,   0 Aug 30 16:31 /dev/mixer

now these were originally 600, but no difference after i changed them.

i also see in my kernel messages:

Feb 10 17:20:19 dhcppc4 insmod: /lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: init_module: No such device
Feb 10 17:20:19 dhcppc4 insmod: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.       You may find more information in syslog or the output from dmesg
Feb 10 17:20:19 dhcppc4 insmod: /lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o: insmod sound-slot-0 failed
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Codec not ready.. wait.. no response.
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Audio Controller supports 6 channels.
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Defaulting to base 2 channel mode.
Feb 10 17:20:19 dhcppc4 kernel: i810_audio: Primary codec not ready.
Feb 10 17:20:19 dhcppc4 modprobe: modprobe: Can't locate module sound-service-0-3

(i think that since the 845 chipset is built on the 810 chipset, many of the drivers
are for the 810 chipset.) so i checked out my modules:

# ls -l /lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o
-rw-r--r--    1 root     root        30572 Sep  4 10:47 /lib/modules/2.4.18-14/kernel/drivers/sound/i810_audio.o

although sound-slot-0 is missing, but that's the second message, so i'm not sure if that's
the main problem.

and

	# cat /etc/modules.conf
	alias parport_lowlevel parport_pc
	alias eth0 eepro100
	alias usb-controller ehci-hcd
	alias sound-slot-0 i810_audio
	post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
	pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
	alias usb-controller1 usb-uhci



and dmesg says:


	Intel 810 + AC97 Audio, version 0.22, 13:45:06 Sep  4 2002
	PCI: Found IRQ 3 for device 00:1f.5
	PCI: Sharing IRQ 3 with 00:1f.3
	PCI: Setting latency timer of device 00:1f.5 to 64
	i810: Intel ICH4 found at IO 0xe080 and 0xe400, IRQ 3
	i810_audio: Codec not ready.. wait.. no response.
	i810_audio: Audio Controller supports 6 channels.
	i810_audio: Defaulting to base 2 channel mode.
	i810_audio: Primary codec not ready.


i'm not quite sure what next to try - any suggestions?

thanks,
michael
