I now have the paid version. There have been a few small and short interruptions, but no longer disturbing. I still have to solve a few other little things, but that is because I am probably very perfectionist.
For now, TuneBrowser is the best working and more importantly the BEST SOUNDING player I’ve ever used. Earlier I compared a lot of music players together with other users. Including JRiver, Roon, HQplayer, Foobar2000, Audiophile UPnP renderer etc.
Mr Tiki, thank you very much!!
