Hello Everybody 
I've got vaio Vgn-AR11B. I have instaled vista ultimate yesterday, and from start i didn't had sound. Later I'd found new drivers for my sigmatel sound card, and everything seems fine until I find out that i don't have sound in games, movies i can't even play any mp3. 
When I'm tryiyng to I get that message :
"Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."
When I'm trying to play movie I get an error that I'm missing DIVX Mpeg 3 layer codec, I had instal it several times but that didn't help.
All I can hear is windows sounds, for an example when Vista is strating, or when I'm opening folder etc.
Please help I had tried everything !!!!
