Yesterday i created a media widget for my sonos players.
Overall it works great, only thing not working is to show the image sonos is publishing.

This is the sonos string i created

String str_sonos_kitchen_currentalbumarturl "Sonos Play:1 Küche Current Cover URL" (grSonos) {channel="sonos:PLAY3:RINCON_xxx:currentalbumarturl"}

This is what it changed to
http://192.168.178.25:1400/getaa?s=1&u=x-sonosapi-stream%3as16342%3fsid%3d254%26flags%3d8224%26sn%3d0

Opened the created url in a normal browser and the right picture is shown, also tried it in openhabs habpanel and the image is correctly shown.

Only media widget didn’t show anything.

Ok, this needs some investigation. Will get back to you.
