Question about Sony STR-DE945 Receiver
I was able to fix this issue by opening up the receiver, removing the circuit board that the power button and speaker selector knob contact, and then reseating that board back onto the circuit board it was connected to (the one with the majority of the control buttons). This completely resolved the problem. The power button works again and the audio does not drop out anymore.

My STR-DE675 has the same problem, I've opened it up and narrowed it down to two audio relays that don't always engage like they should. For me it's the center speaker and the headphone relay. Tapping on them with a screwdriver makes them work again, so maybe this is why tapping on your receiver also worked. I think I will have to install a pair of new relays.

Ok guys I am with you on this same problem mine started with the power button on the receiver not working then it moved to this clicking sound that happens right before the sound goes out. The strange part is that the video still works so it is surely and audio problem. I will keep this page and post if I figure it out.
