have everything installed but have some slight problems That I hope someone can help me with. 1st problem is I have a Creative Sound Blaster external USB sound card and for some reason only the front output is working. Rear and Sub/center is has no signal coming out. Woundering if this is a software problem or am I missing something? I have Zotac MB. 2nd problem I have is my Directed HD radio. I have Centrafuse 3.1 and for some reason I have no sound coming from it when I'm tring to listen to the radio. How I have everything wired up is L/R RCA's from HD radio to input jack on comp. Output jack on computer goes to Sound blaster card input. outputs from sound card go to inputs of 4 channel amp and mono amp. Will post some pick in a bit.
