My components aren't playing nicely together I'm using a Chaintech AV710 to pass sound information on optically to the HK receiver and that works fine for things like .mp3's, .mpeg's etc. in stereo and DVD's using WinDVD in full surround. The problem occurs when I try to use my TV tuner in the ATI card. I don't get any signal over the optical line...I need to plug in standard cables from the line out of the soundcard to receiver and it works fine. At first I thought it was just 'cause the TV is stereo and not surround so maybe it doesn't like an optical connection, but the mp3's etc. are stereo as well and they work fine what the fuck's wrong?
