Okay so first of all the renderer/streamer is a DCS Bartok and I have Asset running on a Windows 10 PC.
I've been trying to use the TuneIn radio option in Asset; version 6.2.

I was first of all using BubbleUPnP on two different Android clients and several (in fact most) stations would not play giving a resource error. I can browse the stations list but when I select a station (not all) then it shows the title page but it won't play and I got an error.
I then tried the Radio service which is built into the DCS app.... the same radio station plays fine.
I then tried the TuneIn service using UPnP via Asset selected via the DCS app... again the station will not play.

It seems three quarters of the stations won't play.

e.g.
Heart 70s (128K MP3)

This station is also as an AAC stream and also won't play when done through Asset.

Help please! :-)
