Hi, all. I've had my Onkyo TXNR905 for 5 years now, and never did try the Audyssey setup program. I completely rearranged my theater and decided to give it a try. I was amazed at the accuracy of the speakers size, levels and distances it calculated, but after the setup was run *all* of my speakers now have a crackle and hum coming from them. The crackle and hum loudness does change with a change in volume, and it's very, very audible. Any idea what the problem could be?
