EDID detection is broken, I can confirm that.

I built a custom EDID, not fun that has only the following modes:

1080p30
1080p29
1080p25
1080p24
720p60

Yet the ODROID C2 finds:
1080p60
720p60

That means it discovers non-existent values from the EDID (1080p60) and simply ignored the 30, 29, 25, 24 which are all that are set as valid.


Worse looking at aud_cap shows (nothing no sound at all), yet I can can verify that:
8 channel PCM
6 channel AC-3
6 channel DTS
8 channel DTS-HD
8 channel EAC-3
Are all present in the EDID, yet it discovered none of them.

the EDID in question is:

Since this was constructed purely to match what I need, was then loaded to the Genfen, and finally verified via a Nvidia card as matching what I entered I can only assume the issue is with the detection on the ODRIOD C2.

I do not know if there is much we can do about it, but I can say that detection is not working correctly (well I'd say at all).

Back to coding an over-ride, but I need help on the build, since I've compiled 7.90, but while that was simple, debugging kodi changes seems like a major chore, I'm hoping for suggestions as to how others handle it. I have to modify Kodi, create a patch for LibreELEC and test it, the submit it, but creating and testing is a giant pain if I need a new build every time since I do not see a way to quickly replace only Kodi, suggestions as to how others do this would be helpful.

Thanks,
