Please let me know if I could expect support of HifiberryDigi+ on Kodi or if it useless to post the issue here.

What was the last build with working HifiBerry Digi+ DD5.1 support? It's probably a kernel issue, but identifying the last working build is a useful starting point.

The issue is it never worked. I started using HifiBerry in OE6.0 and had the same behaviour. Later I was able to get DTS working after some tries and with the help of popcornmix in post #2149.
The VideoPlayer issue seems to be fixed as I'm able to use "sync playback to display" and passthrough enabled and DTS is still working. However DD5.1 never did.

I'm not sure where I should start testing? Should I go back to OE 6.0 builds?
