Streaming problems

Not really a new problem, but one that has resurrected itself after installation of Ubuntu 19.10.
I like to stream music from my desktop to my SONOS sound system and also to stream video and pictures to my Panasonic TV. This ceased to be possible with Ubuntu versions 17.04, 17.10, 18.04, 18.10 but with the installation of 19.04 functionality was restored. However, with the 19.10 upgrade things aren’t working anymore. I checked the SAMBA config file and that seems the same as 19.04. I have switched on the new sharing settings in Settings.
I would appreciate any other suggestions!

There is DLNA sharing inbuilt in 19.10. Try Settings > Sharing > Media Sharing

Many thanks for taking the trouble to reply, but I have already tried this. Media sharing is switched on and displaying as active, but the problem I’m having still remains.
