Windows 10: KB5003637 update - after update, no audio to TV from HDMI cable

I just updated KB5003637. And after the update, the previous TV display audio is missing. I can't find the device anymore. So, I uninstalled this update and the TV display audio is back. But the Windows Update is automatic. So, I have to uninstall this update everytime it gets installed and messed up my TV audio linked from my laptop using HDMI cable. Any way how to stop this?

No audio from TV connected to computer via HDMI cable

Hi Jim,

For us to further assist your with the audio issue on your TV when connected to the computer, please provide the following information below:

• Have you tried to update your audio and video drivers on the computer?
• Have you checked your TV settings if your HDMI settings are set up according to which port the HDMI cable is connected? For example: HDMI 1 or HDMI 2.
• Is the HDMI cable working if you use it on a different device?

Keep us posted.

 

Updated to Version 1803, HDMI audio on TV

Okay, just tried this, Display Audio or anything mentioning the TV isn't on the list:





And the troubleshooter only had options for the same two devices in the tray before:

 

No sound from TV with HDMI cable

Hello everyone,

I've built a desktop recently and everything is working properly until I connect it to my TV. Basically, I have no sound, even though the TV is properly detected by Windows. I have no problems whatsoever when my desktop is connected to my Lenovo high refresh monitor. So, below is how the volume shows up.





I've tried multiple things with no success:

• Updated my graphics drivers
• Tried different HDMI ports (from motherboard and gpu)
• Tried with HDMI cable from TV
• Tried with HDMI that came with my monitor
• Tried Windows troubleshooting
• Tried updating Realtek drivers directly on Device Manager (Windows said I already had the latest drivers)

Below you have an image that the TV is correctly detected and selected:





On Device Manager everything looks okay:





When I tried to see/edit the TV's sound properties basically I have nothing to change, and it says: "that the device was removed" and "no audio device is installed":







On "speakers configuration" on the image below it says "Unknown", which is weird:





Windows troubleshooting fails with two errors: "Volume is too low" and "audio services are not responding"





I have no more ideas, so I appreciate all the help you can give me.

Thank you in advance
