Disable automatic switch to plugged in audio device?

Hi Lucleonhart,

Thank you for posting your question in Microsoft Community.

From the issue description, you are not able to set HDMI as default device. I will be glad to assist you on this issue.

1. Who is the manufacturer of your sound card?

2. Have you installed the latest drivers for the sound card from the manufacturer’s website?

Follow the steps mentioned below.

a. Right click on the sound icon that is present in the notification area (bottom right corner of the desktop screen)

b. Click on Play back devices and in Play back tab, if you can see speakers then right click on it and click enable and then set it to default.

c. If you cannot see the speaker icon in the sound window then, right click on the empty space in the play back window and make sure that the ‘show disabled devices’ is checked.

d. Then follow the step ‘b’ to set the speakers are the default device and enable it.

Check whether you are able to hear sound.

If not, I would suggest you to install the latest drivers from the manufacturer’s website and install it on the system.

I actually have this issue as well I would like to stop the automatic process of selecting my audio devices.. I want to choose my devices not let the computer choose for me..

Their has got to be a way to disable this annoying feature of automatically selecting the audio output..

I have windows 10 pro please fix this..

I use my computer for live recording and playback.

Hello, i do have this problem too. 

For clarrification  here the description from the theadstarter at the end of this post:

I have the same issue, and I can say it is infuriating. 

In my case, rebooting my machine will often times make one of my monitors the default playback device, even though previously I had set this device to 'disabled' in playback devices. 

I have essentially trained myself, every time I reboot, or every time I have to turn the monitors off and on again, to check playback settings and make sure the proper outputs are being used. 

Extremely annoying. Please Microsoft, wtf.
