still looking for advice... I have now tried three different mics to use through vpc - two usb and one that plugs into the mic plug on my powerbook g4. None work. Has anyone ever got any mic to work through VPC???? This is getting annoying, not to mention costly. YES, I do realise there is a built-in mic on a powerbook - this doesn't work through VPC at all (for those of you who were wondering) cheers.
