you see tw0 ACD_SIG in there, and they could be what you want.
Will you then tell us wich worked?

Do I need to extract these to a certain folder?  I used both of them and I still can't get sound.

Hello.  I have the exact same problem with the VGNFE88OE series.  I downgraded to XP and I cannot get sound.  None of the drivers from the Sony site work.  The only one I need is the SigmaTel sound Driver.  I can't read anything on the www.sony.de website.  Can someone directly link me to the driver that worked for the poster of this thread?  Thanks.
