I think I found a bug with the audio in DD+, I added 2 tracks in a project and then I build the project, the result was there was no audio, I've use the tool BDEdit to check the playlist and It was selected the wrong audio type, after edit the playlist manually the audio was working.

As you can see in the previous screenshot there are two DD+ formats and the playlist before been changed by me had selected the 8 position DD+the 5 one was the correct one.

This file is incompatible with Blu-ray UHD specification. I recommend unchecking "Ignore parsing errors for internal muxer" in the Project properties -> Streams, then click "Delete all index files" and try to multiplex again.

And it will not work with the audio you have sent, cause it is incompatible. DD+ support in Blu-ray is very limited. It's recommended to use True-HD instead of DD+ in Blu-ray.

But changing the audio with BDEdit it works, why? And there's any easy way to convert DD+ to True HD?

Internal muxer not intended to work with streams incompatible with Blu-ray specification. If you uncheck "Ignore parsing errors for internal muxer" and delete index files - the mux should fail. If you want to mux streams incompatible with Blu-ray specification - you can enable "Ignore parsing errors for internal muxer" or use tsMuxer, but we do not guarantee that this will work.

PS: regarding the type in the playitem - we will check.

I tried to use tsMuxer but it returns a loop error so I decided continuing using internal mixer
