I have a ONKYO HT-R520 receiver. I am connecting my audigy 2 ZS by using a mini-jack adapter. I can not get any sound to come out, and I have tried EVERYTHING. So my only conclusion is my audigy is defective, the receiver is defective, the cable or adapter is defective. Is there a way to isolate each component and see if they work? Could I test the resistance of the cable and make sure it is working, then test it with the adapter? Is there an easy method of seeing if it's the receiver that can receive the signal, or if it's the audigy not producing it? Thanks!
