Audirvana stops during first or second track (Sony UHP-H1)

Sorry for the misinfo, Integer mode is not the issue here as you are using UPnP.

@Daniel_Norrby, are you also using the latest firmware update of the UHP-H1?

Yes I am. …

I bought a new bluray player in the meantime, that I could try to stream to.
But my trial license has expired.
Is it possible to receive a new trial license key?
