Hello. Just found this link. I have same issue with Yamaha RX V671 and Sony blu ray. Cuts out during loud passages on Fury and The Equalizer. Blu ray works fine direct to TV. Swapped HDMI cables and ports. Thought it was drawing too much power so disconnected subwoofer but problem still exists. I'm borrowing my friends BD player and will try that as next step. I'll keep you informed...
Replaced my Sony Blu ray with a friends Samsung and DVD's worked fine. Went out and bought a Samsung h5900 and it works great. Whew, I thought the receiver had gone bad. Even though it may have been some strange mismatch between the 2 components. Maybe someone can explain how a blu-ray player would work fine with a TV but not well with a receiver. Are the signals that much different?
This thread sounds exactly like a widely reported problem with audio cutting out from streaming apps ... and appears to be a problem with Netflix and Amazon streaming Dolby Digital Plus (DD+) content, which the player/tv then downgrades to Dolby Digital (DD) (which is supposed to be a drop-kick iaw Dolby), but is faulty. On my Yamaha RXV775, the audio cuts out from time to time, indicators blink. It's the player's fault as OP indicated upon replacing the BD player.
