Streaming free-to-air radio to Sonos from tvheadend

I have Sonos Roam and a linux server with a DVB receiver USB dongle capable of broadcasting digital free-to-air radio in my home network. URLs looks like:

A “mpv” player detects it as:

>demux] Detected file format: mpegts (libavformat)
rad] Codec list:
rad]     mp3float (mp3) - MP3 (MPEG audio layer 3)
3ad] Opening decoder mp3float
aad] Requesting 1 threads for decoding.
gad] Selected codec: mp3float (MP3 (MPEG audio layer 3))

Looks very standard and as it is free-to-air - it is definitely designed to be consumed by the stupidest device available on the market for the last 10 years :-)

I tried adding these to Sonos App via “TuneIn”, the app then shows animation like it is playing music but nothing comes out of the speaker. Is this possible at all to play stream like this?
