Question about Sony STR-DB790 Receiver
When I use the input selector, the video signal switches just fine, but all audio playing into the amp is always played out from the loudspeakers. For example, if I have a DVD playing in my DVD player, then press play on my CD player, both will be output from the speakers, even if I have the input set to my PC input channel. Weird, broken, or a 'feature'? Thanks
There is a matrix switching IC on the circuit board that switches and routes the sources. This IC (for the audio) may be damaged, or it is not being properly commanded by the uPC controler. You will have to send the reciever to a qualified service tech to have this verified. Troubleshooting this can get involved if the fault is more than just the matrix IC.
