For some reason my volume control in Windows XP has stopped working and it no longer controls the volume coming from the speakers. However, the 'Wave' slider does control the volume being output by the speakers. It was working fine before I downloaded a bunch of critical updates from MS the other day. I'm running XP SP1 and my sound device is an SiS 7012 Audio Driver. Any ideas would be much appreciated.
Cheers,
Mark
