No problem.
If you can navigate Beoport with these commands and the sound start on your PC. Is it because you have unplugged the minijack from PC sound output to Beoport. You of course need the minijack to minijack connector between your PC and the Beoport. Remember there are 2 simular female minijacks on the Beoport. But you already know that. If you connect the minijack from PC audio- output to minijack on your Audio-in on the Beoport and still dont get any sound in speakers, try to attach a headphone to the front jack on the Beoport.
Any sound there?
When you press N.Music in link rooms, which of the products do you want to play ?. You may have a little conflict because you have 2 mainPC's. If you set the Beoport to Main PC = NO. You of course only can get music from the Beoport in that room, remoting with the IR-eye.
And maybe not? Because its not PC commands but audio commands. I think I have to talk to someone I know would have som good ideas.
I'll be back
