Windows 10: Sound output from PC to TV via MDMI not there and not showing on list

I have an up to date Win 10 (Ver 1909 Build 18363.535 LT), which I have used to watch videos via a MDMI cable to my TV (Vizio 3 yrs old) for many months. Now, with no changes on my part, I can still see the video but get no audio, on the TV, only on the PC speakers. In fact, the TV audio speakers, have disappeared from my sound devices list. I have read on a few help forums and have tried some of the various things mentioned, trying to make the TV speakers show on sound device choice list, to no avail. I've exhausted my limited tech knowledge and need help. If the help is not too complicated, I will try any solution. I have no idea what caused this change of LT/MDMI/TV/speakers settings, as I have done nothing different or changed any settings. Thank you. SR

no Sound on TV device mgr TV shows as media device not under sound


I can cast music to my Sony Bravia XBR 65x850b tv.
However when I have it as a a duplicate display sound I get on the speakers primary display does not come from the speakers on the TV.

On the device manager the TV shows as a media device.
However, the TV does not appear under sound.
Alll that shows under sound is
Speakers
Digital audio (S/PDIF). Digital audio is set as default

How can I have any sound on my PC desktop also come through my TV?

Do I disconnect my Speakers and have the sound come through my Samsung monitor?

What additional info might the list need to help solve this?
