Emby no music playing

I just recently changed form Win10 running on my NUC 6i5SYK to libreelec. Because of performance reasons (it takes 5 minutes to start a song stored on my emby-server at my omv NAS whereas it takes 10 seconds on my Android tablet) and getting a dedicated multi media device.
Setup
NUC running libreelec v7.95.3 beta
Emby add on 2.3.46
NAS Server running omv 3.0.62
Emby Server 3.2.1.0 path substitution added

What ever I do for instance with or without path substitution, direct play or with app music isn't playing. Whereas movies are working. I'm not a dev but when I'm looking at the log I believe something is wrong with the path. But what and how to fix it. Any help is highly appreciated ... I'd like to stay with libreelec and not switching back to win10.

Edit: It's the same for movies. I believe the path is wrong. Why is that in the path? smb://192.168.1.30/movies/moviessmb://Beasts of no ...

Opening: smb://192.168.1.30/movies/moviessmb://Beasts of no nation/plugin://plugin.video.emby.movies/?dbid=68&mode=play&id=6a5d4e89b82ace967b172ccda0dd6da9&filename=Triple.9.2016.1080p.BluRay.x264-DRONES.mk

Thanks

Either something went wrong with scraping your video/music collections, or emby has a nasty bug.

Or you overdid yourself in the path substitution department?

no, tried it already with and without substitution ....

Fixed my problem and it was a wrong path substitution.
For those fighting with Linux here is what I did
- open Windows Explorer
- used exactly the path which is shown when you add a shared network folder
- added it to emby
- reset the emby client
- fresh scan
- worked

With path substitution this is really challenging. You don't need it for Windows, Android but you need it for Libreelec.
