I have had zero luck getting my PSR800 to produce any audio from the system...guess a 996P2 in in my near future.
When I first programmed the PSR-800, it used to track the system but never produce audio. I ended up wiping the memory card inadvertently. When I reloaded the system, the PSR-800 tracked the system fine. At home, I am on the fringe, so reception is not very good. When I take it on the road, it tracks the system pretty well. I still don't know what the issue was before.
