My Vaio got zapped last year and had a new hard drive put in. Everything works but the sound.
I have gone to the Vaio website and downloaded what I thought was the driver for the Multimedia Audio Controller, I must not have done it right.
I have done the Belarc thing and here are the results.
I am running:
Windows XP Home Edition
Vaio Model PCV-RS710G
Board: ASUSTex Computer Inc. P4SD-VL
BIOS: American Megatrends Inc. 2002
Multimedia: Sony MPEG Real Time encoder board
