Angry nForce2 - which /dev's should I be using

Hi There.

Just opgraded to the new nforce drivers.

Before the upgrade I was using the standard i810 stuff - worked fine just out of the box - well after I changed the permissions on stuff like /dev/dsp and set up the module aliases.

The nvnet stuff also worked.

I upgraded so that I could get SPDIF support and indeed I have it - 6 channels too!!!

Nvidia + AC97 Audio, version 0.24, 00:28:58 Apr 24 2003
Nvaudio: in Funcction Nvaudio_init_module
PCI: Setting latency timer of device 00:06.0 to 64
Nvaudio: NVIDIA nForce2 Audio found at IO 0xb400 and 0xb000, IRQ 11
Nvaudio: Audio Controller supports 6 channels.
NVaudio: Defaulting to base 2 channel mode.
ac97_codec: AC97 Audio codec, id: ALG32(ALC650)
Nvaudio: only 48Khz playback available.
Nvaudio: AC'97 codec 0, new EID value = 0x05c7
Nvaudio: AC'97 codec 0, DAC map configured, total channels = 6
Nvaudio: PROBE is done

Now the module is loaded

onix:~# lsmod
Module Size Used by Tainted: P
ide-scsi 7664 0
parport_pc 14148 1 (autoclean)
lp 6592 0 (autoclean)
parport 24992 1 (autoclean) [parport_pc lp]
nvidia 1542144 10
ohci1394 15656 0 (unused)
ieee1394 29964 0 [ohci1394]
nvaudio 25464 0 (unused)
ac97_codec 10216 0 [nvaudio]
nvnet 25696 1

So everything looks good, until I start up GDM and Gnome 2.2

Then when the volume control widget tries to start I get an error

"Couldn't open mixer device /dev/sound/mixer"

now from memory my old set up only used /dev/mixer.

Are there some devices that I need to create to fix this?

One thought does come to mind is that I did partially configure ALSA under the old drivers as when I was running in "vanilla" i810 mode (although patched) I had heard that their drivers woudl work on my hardware and it seemed everyone was using them.

I did de-install them (make uninstall) and purge the packages (I am using Debian) but I wonder if bits, such as where the system should look for sound hardware is, are still hanging around - if this is the case, does anyone know where to look to correct this.

Thanks for any help anyone can throw on this issue.
