Is that something this script can handle?
 

Nope

The script is not meant for dynamic adjustments. It's more about to prevent a black screen if no EDID was fetched at all.

Generally you decide at which point you hardcode the EDID. After that point no adjustments can be done beside hardcoding new EDID informations.

If you want to pass video and audio to TV via HDMI1 and tomorrow want to pass video to TV via HDMI1 and audio to AVR via HDMI2, then that has to be adjusted via the Kodi audio output device setting and in that case I wouldn't recommend the use of that script at all. You also have to do more adjustments to the settings. As your TV might not be able to handle every HD audio format.

It might probably be possible if we can force an output internally (not sure). But as said, as long as that's not possible, we can't even test that.
