Windows 7 audio problems

I am currently dual-booting between xp and windows 7, and i currently LOVE windows 7, chances are that its going to be my next OS. Anyways, i have a Sigmatel audio card (i think) and a intel 945gcl motherboard.

I have used the drivers that came with my mobo (inside came drivers for Sigmatel, so thats why i THINK i have a sigmatel audio card) but when i do that, i only get "cut off" sound. I had a similar problem with vista,i didnt get any audio at the back of my pc (without installing any drivers) only that i could plug my speakers on the front of the pcand everything was fine and dandy.

Are there any "7 compatible" drivers for Sigmatel? Is there anyway to check if i have another card, only that intel packed the disc with sigmatel drivers?

thanks in advance.

Vista drivers are the windows 7 compatible drivers. I noticed that my system likes the generic drivers, if it worked initially. Just make sure you get the 32bit or 64bit, whichever version of 7 you installed, and run the install program under xp sp2 compatibility. Munkyman587
