No sound on Teamspeak
 

I have MSI K7N2 Delta 2 motherboard with nForce 2 chipset and integrated AC97 Direct
Sound. I installed nForce drivers and everything works fine except the Teamspeak.
However, before Slackware, which I have installed about week ago, I used Mandrake 10.0
with the same drivers and Teamspeak worked fine.
I'm using Slackware 10.0 with 2.6.13 kernel, OSS with Full duplex enabled, same as I did in MDK, but now no sound for ts.
I tried ALSA, but every time I enable it, I end up completely without sound at all.
Perhaps I missed something when I compiled the kernel.
