Just to start off with that info, there is an analog workaround for this, but its quite annoying tho I might have to life with that for the time being.
Here is what's going on:
I am running chewitts 12.0.2 for the Odroid-C2 I had lying around since years and discovered the following odd behaviour that pre 9.0 never has been an issue.
I skipped 10 & 11, the last build I ran properly was an 8.something.something and a 9 pre Covid(?).
Whenever the HDMI of the C2 is plugged into the TVs regular HDMI port the whole TV + Receiver CEC / AnyNet+ Audio Return Channel setup breaks and stops working part ways also existing CEC connections become disrupted or entirely broken. The HDMI can be removed while all devices run and sometimes CEC figures that out and recovers. The C2 unplugged from the TV turning both TV and Receiver off and on again usually does the trick anyway.
Funny enough it makes 0 difference if the PulseEight Adapter is activated or deactivated. The issue appears as soon as the board is HDMI connected. (This issue seems to also inhibit any regular CEC functionality between a TV and the C2 like control via the TV remote)
If I want to hear the sound of the C2 over my 2.1 BD HT Receiver I have to unplug the HDMI, start the TV and HTS (connected via HDMI ARC) wait until they figured out each other and sound comes over the HTS and only then plug in the C2 at which most CEC functionality ceases to function on all three devices except direct HTS volume control. As long as I am not changing the HDMI input away from the C2 I can hear the C2s output over the HTS speakers.
This leads me to believe that this issue must be disconnected from the PulseEight Adapter driver AS that is currently deactivated.
Has anyone had any similar issues with their setup recently or in the past?
