Windows 10: Devices with Intel Audio Display Drivers may lose sound from a monitor or TV after updating...

After updating to Windows 10, version 1809, I’m no longer getting sound from a monitor or television connected to the PC via HDMI, USB-C or DisplayPort.

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?

 

HDMI audio disappears after TV power off or change source


Ever since I updated to Windows 10, I've been having this issue.
On computer start up with the TV on and set to the computer source, it works fine. As soon as we switch the TV source or turn the TV off we lose the audio when we go back to the computer source. The Philips TV I use as my monitor disappears from the available sound sources, and I have a red x in the volume setting on the task bar.
Rebooting the computer is the only way I've found to bring the sound back.
This is the exact same computer and TV I used with no issues for over a year before upgrading to Windows 10.

I have installed the latest realtek audio driver listed on this site. I have used the ACER care centre to look for updates, but it says there are none. I've also tried switch out from the realtek to the standard windows driver, but nothing has solved the problem.

I have an ACER XC-605 media PC.
Operating system : ,Microsoft Windows 10 Home 64-bit
Processor : ,Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz
Memory : ,6GB
Graphics device : ,Intel(R) HD Graphics 4400
Audio device 1 : ,Intel(R) Display Audio
Audio device 2 : ,Realtek High Definition Audio

Any suggestions?
