Why does my Denon AV receiver keep shutting off?
I disconnected all the speakers and peripherals, even the subwoofer, but it still keeps shutting off. Sometimes it works perfectly, all audio channels crisp and present, for a week or more at a time before it shuts off. Sometimes it shuts off within a couple minutes over and over for days on end every time I try.
Is the Denon AVR 3808ci the same model?
While the protocol document references a particular model of Denon receiver (AVR-3808CI), the protocol seems to work the same for both models that I have tried to control (AVR-2808CI and AVR-2113CI, purchased 5 years apart). The protocol document reads like an API spec.

What do you mean by absolute volume in Denon AVR?
Yes that is what I meant by “absolute volume”, which can be done just as you say. Its “relative volume”, i.e increase/decrease that is the issue. If you invoke Volume Down, it changes by 1 unit ie goes from 40 to 39.

What is the HDMI port on Denon av7704?
On the AV7704 the only HDMI port used is port 3 that is labeled Blu-Ray by default. This isn’t a complex system. 3) Hitting CBL/SAT on the AV7704 remote returns from the OPPO to the signal originating from the TV with ARC used for audio.
What’s the difference between CEC and Denon arc?
ARC isn’t a control system as such, it is just a contra-flow audio function. You may be confusing it with CEC, which IS a control system over HDMI (and which is also known to be unreliable). It isn’t as simple as one thing ‘pumping out’ audio and another thing detecting it and then turning on.
