Anybody can explain, why this small test file with DTS 5.1 audiotrack:

will hiccup during playback with KODI 17.0 and 17.1 (on an X92 [AMLogic S912] box), and also I get no sound at all with passthrough DTS audio option enabled (the "DTS" icon on receiver display lights up, but all channel icons are off - normally I would see L/C/R/LFE/SL/SC/SR lighted, depending on which channels are present in the stream).
If I enable "encode to AC3" and disable DTS direct output, the sound is okay (multi-channel), but the video still hiccups.
At the same time, it plays absolutely flawlessly in SPMC, no hiccups, receiver happily decodes the DTS stream.
With "real-world" videos with DTS audiotracks I sometimes get no video hiccups, but still no sound if I enable direct DTS output.
I'm not 100% sure, but sometime, long ago, in a galaxy far, far away I've seen the above test video running flawlessly on same box with KODI 17.
UPDATE: Installed kodi-20170411-a4896c0-shitty-armeabi-v7a.apk. The DTS sound is back, but video still hiccups!
At the same time, kodi-20170411-91c472b-notsoshitty-armeabi-v7a.apk - no DTS sound, same problems as in 17.1 release!
UPDATE2: I have disabled "amcodec" video acceleration in SPMC, leaving only both "MediaCodec"; the video still plays fine, so it's not related to Android video acceleration support. It rather looks to me like an audio/video sync problem. Video hiccups in KODI 17 will go away if I disable hardware acceleration (both MediaCodec options), but that's obviously not a solution.
