So i just set up and installed everything, went extremely well. Ended up with about 94 channels, a bunch of them were music and a few HD QAM channels. Unfortunately the QAM channels have no sound. Anyone have any idea why this is??? I have it hooked up to the blackbook, does it not have the right kind of speakers for the job??? I have my eyetv 500 hooked up with my macbook. I get about 4-5 unencrypted stations on the 500, but all of the hd channels have no sound. Could someone please give me some advice??
