Linux and A7N8X Deluxe: audio problems

I've installed Fedora Core 1 on a new PC with an A7N8X Deluxe mobo.
On the initial setup, everything went fairly well, most of my hardware
was detected without problem, and things started up fine upon bootup.
I haven't had a chance to try everything yet (e.g. USB and Firewire
ports), but the two problems that came up right off were the system
not detecting one of the onboard NICs (this mobo has two), and no sound.

It looked like I could fix both problems at the same time by
downloading the nVidia Linux drivers, which had modules for both the
NIC (nvnet) and the audio (nvaudio) (the system, as per
/etc/modules.conf, had been trying to use the i810_audio module).
There was no Fedora binary, so I downloaded a tar file and built from
source (as per the instructions on nvidia's site).

Indeed, everything went fine with the nvnet module, and I got the
second NIC working right away. But I ran into problems with the
nvaudio module. It compiled fine, but when I ran "insmod nvaudio", I
got the following errors:

Using /lib/modules/2.4.22-1.2115.nptlsmp/kernel/drivers/sound/nvaudio.o
/lib/modules/2.4.22-1.2115.nptlsmp/kernel/drivers/sound/nvaudio.o: init_module: No such device
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

I've tried a bunch of things, several based on restarting the system
with certain settings of the kernel acpi and/or apic (uggh, acronym
heaven) parameters, but nothing's worked so far. If anyone can give
me some tips on getting this going, I'd really appreciate it!

(I did actually get sound working when I used sound-slot-1 instead of
sound-slot-0, but then it was only using the soundcore module, not
even i810_audio. And from what I've read, getting the nvaudio module
going is the "right" way to do this.)

BTW, this system is dual boot with Windows 2000, and everything works
fine there.

Thanks!

I've had the best luck with the alsa drivers. Go to the alsa site:
http://www.alsa-project.org/ and select Supported soundcards, pick
NVIDIA, then Driver and Docs Details and follow the directions.
It is a little complicated, but it works well. You will have to
remove the info from modules.conf for the modules from the "bad"
drivers, then edit as shown in the directions to add the stuff
for the new ones. Good Luck.

Agreed, I've been using Kernel 2.6 with the ALSA drivers (intel i810 again)
and they've been fine.

Well, OK, I tried to use the alsa drivers. I followed the directions
on the nVidia page, and everything compiled and installed fine. But
when I got to the insert modules step, I got the same error I got with
the nvaudio module:

/lib/modules/2.4.22-1.2115.nptlsmp/kernel/sound/pci/snd-intel8x0.o: init_module: No such device
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
/lib/modules/2.4.22-1.2115.nptlsmp/kernel/sound/pci/snd-intel8x0.o: insmod /lib/modules/2.4.22-1.2115.nptlsmp/kernel/sound/pci/snd-intel8x0.o failed
/lib/modules/2.4.22-1.2115.nptlsmp/kernel/sound/pci/snd-intel8x0.o: insmod snd-intel8x0 failed

Here's the tail of dmesg (I think it's got all the relevant parts):

Intel 810 + AC97 Audio, version 0.24, 15:28:15 Oct 29 2003
PCI: Setting latency timer of device 00:06.0 to 64
i810: NVIDIA nForce Audio found at IO 0xd400 and 0xd000, MEM 0x0000 and 0x0000, IRQ 11
i810_audio: Audio Controller supports 6 channels.
i810_audio: Defaulting to base 2 channel mode.
i810_audio: Resetting connection 0
ac97_codec: AC97 Audio codec, id: ALG32 (ALC650)
i810_audio: AC'97 codec 0, new EID value = 0x05c7
i810_audio: AC'97 codec 0, DAC map configured, total channels = 6
Nvidia + AC97 Audio, version 0.24, 00:03:16 Dec 30 2003
Nvaudio: in Funcction Nvaudio_init_module
Intel ICH soundcard not found or device busy

Actually, upon further examination, only that last line is from this
modprobe/insmode call, the previous lines are from when I attempted to
insmod nvaudio.

So, perhaps the same thing that's keeping me from being able to insert
the nvaudio module is keeping me from inserting the alsa modules.
Anyone got any ideas what that might be, and how I can get around
that? Thanks.

Solved!

The problem was that an existing module (in this case i810_audio) was
conflicting with the new module I was trying to install, and I had to
remove it first. Finally after searching seemingly hundreds of
pages/posts I found one that mentioned the idea of removing modules
(using rmmod, with perhaps the -r option). That was the key.

And actually I couldn't remove i810_audio, because it was busy. So
what I ended up doing was removing the lines from /etc/modules.conf
that caused that module to be installed in the first place, and
rebooted. After that, I was able to complete the installation of the
alsa drivers (and I bet it would've allowed me to install the nvaudio
module as well).

It took a bit more wrangling to get everything going, but now I'm
happily listening to the Who's Tommy while I type this. (Too bad the
monitor's speaker is so crappy, but that's easily remedied :-).

BTW, I found the important piece of info on the following nVidia/Linux
forum (and it looks like it's got lots of other helpful info):

Thanks again.
