Windows 10: Audio automatically transfers to laptop when I extend to a second screen

I use my laptop as a 2nd screen. Since the recent big update to Windows 10, my audio automatically transfers to the laptop when I extend to the 2nd screen. As I have my computer connected to my stereo system, this is a large issue - particularly since the audio on my laptop isn't great. How can I keep this from happening. Audio is Realtek. Computer says driver is current

no audio on extended display

Is your computer’s Operating System updated?

How about your Audio drivers, can you check if it is updated and can support HDMI audio output?

If your answer to those questions are yes, then you can check these steps to setup audio for your extended display:

• Connect your laptop to the extended display using the HDMI cable.
• On the lower right side of your task bar, right click on the Audio icon.
• Select Playback device
• If you don’t see your extended display (T.V) you can right click on a blank space on the Playback tab and select Show Disabled Devices and Show Disconnected Devices.
• One your extended display (T.V) is showing, please check if it is enable.
• Then Select OK.

Do a test and check if the audio is now playing on the extended display, if issue still persists, try to restart your computer without removing the HDMI for both devices.

Let us know how it goes.

 

Returning Windows to Second Screen

Hello Kate,

Let's try to isolate the issue and see what is preventing you from using Windows to second screen. Kindly provide us the following information:

• When you turned on your computer, does it give you an extended display for both monitor screen and your laptop?
• Is your monitor screen already connected to your laptop before turning it on?
• What cable are you using to connect your second monitor to your laptop?
  
• What troubleshooting steps have you tried?
