Thank you for the quick answer.
No, there are no error messages on the screen. I have set the suggested setting to “no”, but played too short to give a result.
It’s not that I use a very long playlist, but select every album and usually listen to it in its entirety.
That sometimes goes 5 albums in a row without a malfunction, but it can also go wrong with the first album and the first track. Usually the music starts playing again after a short or longer period of time. Short is within 5 seconds, long is sometimes even after 5 minutes. It is also difficult to pinpoint where the problem is. Is it TuneBrowser or is it Qobuz or our internet provider. I never had the problem with my previous player, but the whole song was loaded into memory. This is a setting in JRiver.
I found TuneBrowser on the Audiophile Style Forum. And it really is the best sounding. Resonance of instruments and naturalness of sound are extremely good. Micro information is passed on very well. Much better than Roon, JRiver and for example Audiophile UPnP Renderer. I also tested Volumio and a lot of other Linux players, but they often had problems with the software of my Pink Faun i2s sound card. However, this works perfectly with TuneBrowser under Windows 11.
