squeezebox addon does not work

  • No process with squeezelite is running.

    On the terminal I listed the available outputs

    and I could start a squeezeboxserver with

    Code
    squeezeboxlite -o default:CARD=PCH

    So I want to change the audio device in the addon from auto to default:CARD=PCH

    but I get an error, see log file.2019-12-16 18:59:53.950 T:140152416491264 WARNING: Previous line repeats 83 times.

    Looks like the default addon permissions are not correct...:/

    What permissions should be set?
