Thanks for the on screen Radio button and BBC sub folder, however they are the low bitrate (96) versions of the stations.

Any chance you could replace these with the higher (320) bitrate versions?

WiiM probably can't differentiate between UK and Rest of the World users so can't use the 320kbps streams.

Try using the links referred to in this post in Open Network Stream, or use the bbc sounds app and Chromecast or even airplay to your WiiM.

Should have stopped there; this is an ultra firmware thread after all...

Hi @Jamiewednesday

We will check these versions of the stations. Usually, their bitrate should be 320kbps.
