Absolutely. sounds reasonable. But until now, I did not check any logfiles. I only tried to find a reproducibility.

OK, thanks. On my setup, the decoder always throws an error when playing back DV 7 files from Emby.

Code:

12-28 01:12:24.797 21286 21351 D NvOsDebugPrintf: Dolby Profile is 80 and Level is 0
12-28 01:12:24.797 21286 21351 D NvOsDebugPrintf: Profile 128 not supported

Profile 128 corresponds to DV7 (1<<7 = 128).
AFAIK, Shield only supports single layer DV profiles, that is profile 5  and 8. So it seems like getting it to play DV 7 at the moment is moot.
WRT to Kodi, it has to implement the missing functionality to either propagate the profile and level info to the decoder, or, if that is the case, work on the demuxer to make sure it isn't leaving anything out.

Where shall I open the issue/s?

Maybe github? I don't have a repo.

If I am right profile 8.1 doesn’t support HD-Audio, because it’s mainly for streaming normally.

I believe this depends on the container. Seems to be working fine with MKV.
