Aloha to all... I have a Yamaha RX-V 550 reciever with a set of wharfedale speakers...8.4s front, 8.1s rear, 8 center and a Powercube 10A sub. In my SAME living room and in the same corners was my OLD setup of CREATIVE CAMBRIDGE SOUNDWORKS 5.1 speaker setup which was connected to my COMPUTER (also in the living room). Well..the creative setup HAD to go...too many wires ...and i was hoping of connecting the PC to the reciever.... I have a few questions: 1- I used a wire which on one end looks like a headphone plug and on the other end has 2 RCA plugs..one red , one white....and connected these RCAs to the "CD input on the receiver"....IS this RIGHT??? 2- Should I have plugged it into the MDTape Recorder input instead?? 3- The soundcard on my PC is a soundblaster Live! 5.1.....the plug went into the "BLACK" output on the card....I left the "GREEN" "YELLOW" "BLUE" "PINK" outputs empty.....I can hear sound when I use "CD" on my amp.....BUT I WONDER...AM I GETTING 5.1 SOUND??? FOR EXAMPLE...IF I PLAY doom 3..WILL I GET 5.1 SOUND?? 4- aM i PLACING THE AMP UNDER ANY DANGER BY CONNECTING IT TO THE pc?? thanks!!
