Incompatible elements

[melwinek]

When I switch the output to the browser it's ok, but when I switch to Google Mini. There is a message that incompatible components have been hidden. The same streams selected from RadioBrowser work fine.
What could be wrong?
My config:

netradio:
  radios: 
    - url: 'http://195.150.20.242:8000/rmf_fm'
      name: RMF FM
      icon: 'https://www.rmf.fm//inc/img/favicon/ms-icon-144x144.png?2'
    - url: 'http://zet-net-01.cdn.eurozet.pl:8400/'
      name: Radio Zet
