Android Video & audio out of sync after a couple of minutes
I've been chasing this trouble for quite awhile also.
As you say disabling Media codec acceleration stops the loss of A/V sync, but I've also found that if you change
the android setting in preferences/playback to output video from OSD Layer to video layer the trouble changes.
Instead of A/V sync loss the video freezes and the audio carries on for 10 seconds.
Then a resync happens, but 7 minutes and 57 seconds after resync the trouble repeats.
Leaving the android setting at OSD layer the A/V unsync happens at the same 7 minutes and 57 seconds but does
 not reset unless you seek back the video a few seconds.  Then from that point it happens again at the above time interval.
My Leia 18.8 was an overwrite install of Krypton 17.6 which never had this trouble.
I have a X8h with Finless Bob ron 1.0 and a X8H Plus with Minix Lollipop rom both running Leia 18.8.
Neither of these boxes have this trouble.
Just letting you know you're not alone.
