I can see audio drivers for the M320 for Windows XP, but none for Vista at Gateway's Support site.
I have to ask how this Vista upgrade was done. Did you ask Gateway whether this machine was compatible with Vista and if so what additional drivers were needed?

i have successfully used windows xp for years on my gateway m320. xp crapped the bed, so i started using vista. i like vista with one large exception: no sound. vista says that the driver appears to be working properly - vista is showing the device as realtek AC'97 audio - but there is no sound.
