Question about Yamaha R-V905 Receiver
Two things I think are happening. It is overheating and it has suffered some sort of damage to a component inside. Try to make sure there is ventilation on all sides. Can you remember a time where you did not have adequate ventilation for this device? If so maybe that is what caused the part inside to fail.
Hope this helps
Thanks for reading!

I can't find a manual but I'll take a stab.
When you say it fades are you being literal? In the digital world things usually change suddenly or stop altogether.
I'd look at the receiver for an indicator that indicates the multichannel nature of your incoming digital audio. Many have little maps or icons showing the number of speakers supported at any given time. That's a function of the incoming data stream and/or whatever the audio source it carries. For example, when loading a DVD I usually see 2.1 indicated on my unit while the low-tech menus and previews are active. Once the multichannel program commences the 5.1 indication lights up.
It almost sounds like the digital bitstream is being corrupted and the receiver shifts down to whatever it can manage to decode from it. Check the cabling that carries the audio. If it's optical instead of copper, I'd check to make sure there are no tight bends or kinks in it anywhere.

Have you looked at the manual? There is no internal source that would produce 7.1 audio other than the test tones. Attach a multichannel source according to ITS manual.
