Minim Streamer stream converter field blank

[IDM]

I tried to stream to both my i phone just as a test and then to my normal streamer which is another Rapberry Pi running Volumio software with an external home built TDA1541a I2S DAC.

Plugplayer can see the BBC stations but When I tried to stream radio to the I-phone, Plugplayer showed error 4. With the Volumio based software there was no error code, it just did not stream and pressing play would not work. Both devices work fine with the MinimServer streaming FLAC files from a hard drive.

Ultimately I would like to get the MinimStreamer to work with a Naim streamer as well.

Cheers
Ian
