Sound in SuSE 9.0

Hi all! Im trying to have TeamSpeak and Quake3 to work at the same time on my SuSE 9.0 pc. I have searched the internet for info but nothing seems to help :( I have an Nvidia Nforce2 motherboard with integrated sound. The latest Nvidia drivers are installed. TeamSpeak by it self is working fin and so i Quake3. But if i start TeamsSpeak and the start Quake3, Quake gets no access to the dev. = no sound. TeamsSpeak whants to send and receive, quake gets locked out. How do i solve this? Ive seen stuff about linking devs around, i have tired but it doesnt work for me. To be honest i cant figure out how sound in Linux works :D Regards /Mattias
