Renderer not detected as featuring gapless

Hi there,

I am the author of the Android app ‘USB Audio Player PRO’. It features a UPnP renderer and supports the setNextAVTransportURI() call for gapless playback. Now this works well with other clients such as BubbleUPnP, but I don’t see Audirvana even attempting to use it. The Media Renderer Analyser also shows that our renderer supports setNextAVTransportURI.

So the question is, what does it take for Audirvana to understand that a renderer supports gapless playback?

Hello @extreamsd,

Can you send me a copy of the “Debug Info” while you are playing some music? You can get it in Audirvana Settings>General>Debug Info

Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message

Pasting didn’t work since new forum users cannot post more than 5 links, so I have put it on my website:

http://www.audio-evolution.com/downloads/audirvana.txt

It says “nextURI: NOT_IMPLEMENTED”, although it is implemented and works with other apps. So it’s probably a matter of how we let the UPnP client know that our renderer does feature nextURI.

I changed your settings, you should be able to paste it now.

Thanks.
