ForkTong, When you say "the speaker" are you referring to the Center Speaker?

Can you give me anymore information, like is the sound hardware accelerated? software? Does it use OpenAL? EAX? Miles?

Maybe with some more information I can start to better trouble shoot why I am not getting voices in the center channel.

Can anybody who is using a creative card and is getting correct surround sound post here?

Lots of question marks there!

Thanks for any help!
