When setting my sound card to a 5.1 surround sound TS v2 bombs with a General Fault Exception.

I had to set it to a 2.1 sound system as a work around.

My system is:
AMD 6000+ t2
SLI-DELUX Vista ready on board wireless
NVidia 8800 GTX overclocked
2 gig corsair dominators
Sound Blaster X-FI extreme
Logitech G5300 5.1 sorround sound

On board Max System is disabled

I will be more than happy to test any beta to help resolve this issue.

I really want to be able to play games in 5.1 surround with Teamspeak on. ( I don't want TS in surround if possible )

Thanks
Nick
