Windows 10: LT MDMI to TV no audio on TV

I have an up to date Win 10 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 watch the videos but get no audio on the TV. In fact, the TV audio speakers have disappeared from my sound devices list. I have read on a few help forums and have tried the various things, to try to make the TV speakers show on sound choices, to no avail. I've exhausted my limited tech knowledge and need help. If the help is not to complicated, I will try any solution. I have no idea what has caused this change of LT/MDMI/TV/speakers settings, as I have done nothing different or changed any settings. Thank you. SR

Sound issues after connecting my TV to my PC using HDMI cable

Hi,

Thank you for contacting Microsoft Community.

I would suggest you to refer to the mentioned steps and se if it works:

• Connect your Laptop to the TV and turn everything on
• Right click on the speaker icon, on the task bar.
• Choose Playback Devices. (You will need to be connected to your TV first to see it listed here).
• Click the Properties Button with the TV highlighted in the list
• Click the "Advanced" tab
• Here you can set the default format for audio playback.
• 
  
  By default this will be set to the highest quality . You can try each level and use the "Test" button to see if it works.
  
  Hope this helps.
  

 

Audio lost to HDMI on LG smart tv.

After the upgrade to 10 I no longer have HDMI audio on my LG Smart TV. I have tried several ways to restore it. I do have sound to the speakers plugged in to my sound card but prefer using the audio on the TV. Any suggestions?

Hi Nilesh,

Please answer these questions to assist you better.

• How exactly have you connected your computer to TV * through HDMI cable * Bluetooth * Miracast?

I would suggest you to install all pending Windows and Audio driver updates in your PC and check.
