Not sure what you meant by transmitting your MP3s but if you want to connect your PC to your HiFi so that the PC's sound comes out of its speakers you could use this [ click here ] assuming your HiFi has an optical input
Thanks everyone. Medicine Hat - I am really looking for something that will transmit my music to equipment anywhere in the house and garden without any wires. I also would like mto know what equipment is to be used on the receiving end,(or does the transmitter send on a frequency that can be picked up by television and radio). I am poring through every bit of documentation to see if the Graphics Card supports VIVO.
