Guys thanks for trying to trace the cause of the issue. The problems do indeed start from PR13301, but I think there are other later changes that have effects too.

Beta3 still has problems, I was unable to come up with a fix in the time available, but it does have some changes that will effect this mixed playlist regression (PR14478 - a fix for game launch bug, that solves a bigger issue!). I think this does improve things, but is not the whole cure.

It is not so much about viz failing (that is a side effect), but that the natural flow though the playlist, as opposed to skipping with next/prev, is not working on mixed playlists. I think the player swapping and clean up is getting things wrong now that it happens asynchronously, so timing could also play a part (and makes locating the issue harder). Sometimes the video player is left to play audio, which it can do but you don't get a viz. Othertimes things don't play at all because they get stopped before they start.

I hope some other team members will advise how the new asynchoronous application control of the player design was intended to work, because just following the code in debug what I see makes no sense to me.

Agreed, I see issues with videoplayer playing things I think PAPlayer should be playing ( as they are audio only).  Perhaps @fritsch and @FernetMenta will be able to shed some light on this, being the foremost audio and video devs (yeah, I am creeping here lol ).

Irrespective, due to testing some other stuff, I now have a clean install from master with no video or music database sources. I've got music-videos and straight audio only (in multiple formats) available so can test pretty much any scenario should you need it.  Debug logs always available
