I have an Audigy 2 running on a MSI K8T neo motherboard with a AMD64 3200+ CPU. The Audigy works under XP on the same PC and under Gentoo running 32-bit on a different PC.

I have compiled the soundcard as a module and not as a module in the kernel (2.6.3) and it the modules load successfully, and it is detected by Gentoo. However, I don't have a

Perhaps you should consult the ALSA howto guide in the Gentoo documents.

Is the OSS emulation enabled in your kernel config?
/dev/dsp is OSS, not ALSA...

BTW, ALSA doesn't like IOMMU support for some soundcards, so you may want to turn it off (but I'm not sure if it's even available on Athlon64 CPU's).

I've set-up this device on Gentoo several times before under various kernels and haven't had any problems. I have tried it with OSS emulation on and with it off, still no dice.

Are you using DevFS?

I've got an audigy 1, no problems here.
Use the 'genkernel' config to compile your kernel, and
emerge hotplug ; rc-update add hotplug default
Which should make it auto-load the modules, you will
also probably want to rc-update add alsasound default
to make sure the oss emulation stuff gets set up...
Anyhow, that'll give you a starting point.

Then use 'alsamixer' to turn up the volume levels on everything,
and play a .WAV file with aplay to verify it's working at a console
level before you try it inside of X/GNOME/KDE.

You could try manually creating a dsp dev file somewhere else as root:

I just had this issue. In KDE select the control center icon -->sound and multimedia-->sound system. Click on the hardware tab change device from autodetect to Alsa.

I take the liberty of assuming you went through the ALSA config guide and that you are using KDE.

I was having all kinds of problems with my install, so I redid it. Now everything works. Thanks for the help though!
