TV outputs sound via optical only during sound test
I just got a new integrated amp and when I connect the optical out from my Samsung PN58C550G1FXZA to the amp I don't get any sound. When I connect a CD player to the amp optical in using the same cables I get sound, so I know the cable is good (have tried 2 diff. cables). Here's the kicker, when I do a self-diagnosis on the sound (via menu settings) it plays sound out of the speakers! That makes no sense.
I have it set to TV speakers because no sound comes out using external speakers. I initiated a chat with Samsung support and they said I needed a technician. But I get sound during self-diagnosis sound test. Any ideas on what could be wrong. Has anyone seen something similar on other TVs? Everything was working with my old amp. Same cables, same TV, etc. All I did was switch out the amp. But the optical in on the amp is working.
Thanks in advance.
