This topic has been raised before (Dec 2023) but the answer there no longer works. I often use my Sonos system (Play5 2nd gen pair and a Sonos Boost) to play internet radio. 

I have used Radio.net, TuneIn and MyTunerRadio as Sonos Services. Over time all these have stopped streaming my radio urls! MyTunerRadio was working well but has now gone. TuneIn has not worked for me for a long time and the new TuneIn does not work either.

I was wondering if anyone has found a fix for this. I have a Raspberry Pi running MoodeAudio - that works well with internet radios - has anyone tried connecting the output from that to Sonos. Has anyone tried VLC and airdrop to a Sonos uPNP server?

Any thoughts much appreciated!
