windows 10 upgrade no sound through hdmi. LG Tv isn't showing up in sound playback menu.

After upgrading to windows 10 from 8.1 my msi gt70 notebook with gtx770m card is not passing audio through the hdmi. The sound preferences don't show the TV as a playback device. And it isn't showing up under audio hardware in the device manager. The gtx770 control panel has audio through hdmi enabled.

Opening up the device manager, the tv shows up as ageneric pnp monitor under displays and as lg webos tv under digital media devices. Under details for lg webos tv the status for No connect sound is <true>.

Any help would be greatly appreciated.

Hi Billel,

Thank you for posting in Microsoft Community.

1. Is the TV Digital Living Network Alliance (DLNA) enabled?

2. What is the make and model of the TV and the laptop?

3. Are both the devices connected to the modem?

4. Are you able to connect the laptop and the TV using an HDMI cable?

I suggest you to install the updated Microsoft Display drivers and check if it helps.

Method 1: Clean Boot

Perform clean boot to identify if any 3rd party service is causing this issue:

Note: After performing the troubleshooting steps in clean boot, follow Step 3 from the link to start the computer to Normal start up mode.

 

Note: Also applies to Windows 10.

 

Method 2:

Disable the security software temporarily and check if it helps.

Note: Antivirus software can help protect the computer against viruses and other security threats. In most cases, you should not disable the antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time the antivirus software is disabled, your computer is vulnerable to attacks.

Let us know the status of the issue.

Thanks.
