Hello,  
Gapless playback over DLNA-/UPNP Renderer seems to be not supported in Volumio 😠  
It works with a mounted network share…ok, but I wanna stream the music as bitperfect 24Bit-PCM stream from JRiver via DLNA through ALLO USBridge to the DAC.  
For me this is the most audiophil and best sounding way and I can also control playback on Volumio over JRiver with GIZMO like a ROON Bridge.  
I know that JRiver supports SetNextAvTransportUri which is required for pre-buffering the next track. I think that function is missing in the implementation of Volumio´s UPNP-Renderer?  
Setup:  
Zotac CI540 Win10 with JRiver MC23 (Controller for music database)  
ALLO USBridge with Volumio 2.513 (Sparky)  
Antelope Zodiac Gold 32Bit/384KHz DAC

I also missing this feature for manual track changes. If bitdepth and samplerate are the same it shouldn´t be necessary to stop the output-signal. But I think this could also been solved by supporting SetNextAvTransportUri.  
A fade out/in option would also be nice during manual track changes without stopping/restarting the output stream.

I hope gapless playback for UPNP/DLNA will be supported in a next release because I think gapless playback is a must have for an audiophile player with UPNP/DLNA support 😉

Best regards,  
Holger

Hi michelangelo,  
nice to hear that…I can´t wait for that to listen over DLNA/UPNP without drops 😃  
Best regards
