I have a Pio 434HDE (no speakers), which is hooked into a Pio C501 receiver. The receiver happily switches the screen inputs and sound between STB, DVD etc. Now I want to hook my PC in, using the PC input on the front of the media box. This is fine, but what can I do about the PC sound? I can plug it into the media box, but then there are no speakers for it to connect to. I could connect it to input 4 of the receiver, but then selecting input 4 on the receiver will not switch the screen to the PC input using SR+. I would need to disable SR+, select the sound source, then select the PC input. Am I understanding this correctly? Is there no easy, automatic way to hook up a PC, routing the sound through the receiver, and selecting simply as I do with the three other sources (STB/Scart, PS2/Scart, DVD/HDMI). Thanks for any help!
