Help required to stream BBC Radio to Sonore Rendu, using Bubble UPnP controller

[DavidL]

I have carefully followed the instructions at "Playing BBC HLS radio streams on a UPnP renderer" without success so far. I have MinimServer and MinimStreamer installed on a Synology NAS.

In the past I have successfully installed the 3 Linn playlists (classical, radio and jazz) by inserting a ".m3u" file into my music library list of folders. These have URLs specified directly (89.16.185. 174:8000, 8003 and 8004). To get this to work I had to disable "Mime-type check" in "UPnP tweaks" in BubbleUPnP.

I tried modifying the BBC Radio.m3u file as suggested in another thread by inserting ";aac" but this did not help.

The BBC Radio playlist appears in the BubbleUPnP control screen but if I choose a station to play the 'play' arrow remains on for 2 seconds before reverting to pause. There is no sound output.
Each time I change anything I exit MinimServer in BubbleUPnP and re-scan the music library before re-testing.

As I already use stream transcode to convert ALAC to 24 bit WAV I'm reluctant to try *:L16 or *:wav as I guess the '*' means everything.

Any thoughts on sorting this out would be gratefully received!
