Hi there.
I’m back with an issue that I already reported back in January 2019 in the Beta forums: [TESTING] Kodi 18 (Leia) builds for Vero 2 & 4K - #918 by Dedi
At a specific Verio 4k build (348), most of my Dolby Digital Plus encoded audio stopped beeing played by my AVR (Pioneer VSX-923) using passtrough. The AVR starts blinking and no audio comes out.
- While a few DD+ Videos still work, most of them stopped at that time.
- Before all were working without any problems (build 344 and everything before). For a long time I kept going back to that build after a lot of update attempts.
- It works when I use Kodi on my MS Surface with the same cable and AVR as the Vero4k uses while playing the SAME file.
- I changed cables, tried any relevant setting, reinstalled completly. I also tried the new Lock HDMI HPD setting in the October release.
This points to a direct Vero4k or OSMC issue as Kodi itself seems not to be the cause. I already narrowed it down to the exact build back then. 344 works as well, 346 and 347 are builds that crash, and build 348 has the audio problems.
For this post I did some further testing:
All DD, DTS, DTS-HD MA, TrueHD streams that I tested were working without problems.
Dolby Digital Plus: 5 full seasons of different tv series and most movies don’t work, while I found 1 tv series and 1 movie that does work.

Probably someone else with same problem: Dolby Digital Plus passthrough Pioneer VSX-922
If I can provide some more helpful information, please let me know.
