Help streaming the audio only from a TV stream please

[tarmacalastair]

Hi,

Audio-only feed for BBC News TV channel

I have a TV streaming box (Vbox) which takes live broadcast TV (DVB-T/DVB_T2) from the aerial and streams it around the house over LAN and wifi. I can view TV from this using VLC, Mythtv, Kodi, etc on PCs, laptops, phones, etc....

But what I would also like to do is just listen to the audio from the television channels (not just the radio) over either my LMS (LogitechMediaServer)/Picoreplayer system or my Sonos portable (Roam) wifi speaker. Both of these systems allow you to enter the URL for an internet or local audio stream to play to the connected clients, either squeezebox (PiCorePlayer) or Sonos speaker. I have a Sonos Roam but it is also connected to the LMS so can play back from either the Sonos network or LMS.

Can anyone help please with a way to get the audio-only stream from my internal stream that comes from my TV streaming box (Vbox)?

The URL for the feed from my local box looks like this:
http://192.168.xx.xx:55555/ChannelList.m3u8 for all channels.

If I open this in a text editor, I can find individual TV channels which look like this:

For the BBC News channel:
http://192.168.xx.xx:55555/BBC%20NEWS

These feeds play back fine in VLC and Kodi but I just want the audio to stream to a speaker! But I've tried putting the URL into the Sonos interface (adding a radio station) and it just plays crackles and pops and LMS just doesn't accept the URL at all, unless perhaps there's a plugin that I don't know about.

Failing this, has anyone worked out how to stream just the audio from BBC Iplayer?

With all the recent Covid news and now war in Ukraine, we seem to have the BBC News channel playing on TV an awful lot but if I leave the room where the TV is I'd like to be able to keep listening without a screen device.

Can anyone help please?

Please don't suggest:
Bluetooth - this does not have the range around the house and it would cut the sound from the TV speaker so my wife would complain!
BBC World Service radio - as great as it might be, it's currently broadcasting a programme about cookery - not exactly breaking news! And I would like to be able to continue listening to the same programme on TV and elsewhere in the house. (And ideally I'd like to stream audio from any TV channel too, not just the news channel)

Many thanks for reading.
