I got a problem with my Intel NUC6CAYH (based on Apollo Lake, Intel® Celeron® CPU J3455). Whenever I try to run LibreElec (doesn't matter which build, I tried release-8.0.2, Milhouse daily dev, Kodi/Agile Leia) everything seems to work smooth EXCEPT LiveTV.

For LiveTV I use TVHeadend (tried DVBViewer too, same result) and when I enable VAAPI (hardware-decoding) it looks like the video is playing in slow-motion or something, audio is completely out of sync and every now and then audio skips. When I switch off VAAPI it works fine, but obviously I didn't go Apollo Lake to disable hardware-decoding

I'm beginning to think the hardware-decoder of Apollo Lake can't somehow handle the Live-TV stream. My LiveTV streams are both MPEG2 (SD) and MPEG4 (HD) and they both suffer the same problem. They are all 50 fps (I'm from Netherlands, so 50 fps rather than the 60 Hz. from NTSC). I've tried framerate syncing to display turned on/off, tried all settings I know off (e.g. audio pass-through on/off) and I can't get it to work with LiveTV except when I turn off VAAPI, then it is immediately all good.

I wonder, anybody else experiencing this or knows how to fix this?

Personally I don't believe that neither the Apollo Lake CPU/GPU nor that LibreELEC is the issue. Iam using a J4205 which has very similar capabilities and decoding of in my case german DVB-T2 (HEVC) streams runs smooth as butter. Have you tried changing your TV-card/stick? I assume that the TV card/stick could cause the issue.
