Troubleshooting an Annoying Problem w/ Denon AVR-X7400h

[SuicideSquid]

My Denon 4700h has recently developed a very annoying problem and I've been unable to find a fix for it - hoping one of you lovely folks might have an idea.

When I turn my system on, the receiver defaults to TV Audio input (good, as 90% of the time, I either use the TV for streaming, or my PC which is connected directly to the TV and the audio is then sent to the receiver via HDMI ARC, so I want it to default to TV Audio).

However, about 20-30 seconds after powering up, every single time, the receiver switches the audio input to HEOS Streaming, and I have to grab the Denon remote and manually switch it back to TV Audio (or whatever other input I'm actually using).

This behaviour started a couple of months ago when I played around with setting up a HEOS account, but I almost never actually want to use HEOS. I've uninstalled the app from my phone, so it's not receiving a blutooth/wifi signal from the app. I've searched the menus to try and find any reason for this behaviour and come up with nothing.

The only thing I can think to try that I haven't done yet is a full firmware reset, though I'd prefer not to do this because I think it'll mean re-doing my Audyssey room setup, which is a pain.

Any suggestions? Thanks in advance!

FWIW your title has 7400 instead of 4700....

Following but I haven't had that issue with my 4700. I never did setup a HEOS account nor use HEOS generally for that matter.

Doing a firmware update generally won't reset your Audyssey setup IME. OTOH I generally turn updates off unless I need one. Doing a full microprocessor/factory reset does reset everything back to default, though....maybe try just a soft reset (unplug the avr from power), for a minor glitch that may be enough.
