Project Slimbox has created an ATV ROM for most of the Amlogic boxes that DOES support the HD audio codecs under Kodi.  He also includes Afrd for automatic framerate switching..... I prefer his ROMs.

Interesting. Have you tried this? I don't see any mention of hd audio on Xda. Also seems to support only very specific boxes. But this is great work, thanks for the link.

I am running it on my Beelink GT mini2, and yes under Kodi it plays all the HD audio codecs, just like CoreELEC. Also, using the arfd system app, I get automatic frame rate adjustment, again just like CoreELEC.
If you look at the website where I showed you, you will see lots of Amlogic boxes that are supported.

Thanks, thats great to hear. So do you now use Android rom or do you still boot into CoreElec?
Was thinking of GT-King but its not in supported list and in the thread someone else asked about it but no replies.
