Playback through a Squeezebox Radio often breaks off

Hey,

I'm using a RP4 with an Picoreplayer 6.0.0 an everything ist working fine while playing Music through my SB Touch.

But unfortunenately I have some problems streaming through my SB Radio. Usually I'am starting the stream through my Ipeng-Control (Iphone). The stream often breaks off and it continues while touching any switch or controler at the radio.

I have no Idea to fix the problem.

Greetings
