Just installed it on a PC and it works fine.
You have to right-click on the SWYH icon, then select “settings”, check the box “use specific http port”, then go back to “tools” “http live streaming”
this shows a small screen on which you click “copy”
You go the Sonos app on the PC and select the “manage” menu, “add radio station” and paste this link.
The only issue is the 2 second delay.
