Can W11 send audio to two devices simultaneously?

Hi. I'm David, and I'm happy to help you.

Yes. This is possible.

Follow the steps below:

1. Press "Windows + R", type mmsys.cpl and press Enter;
2. Select the "Recording" tab;
3. Check if you have the device "Stereo Mix", right-click and select "Enable";
4. Double-click on "Stereo Mix" to open the properties window and select the "Listen" tab;
5. Check "Listen to this device";
6. Under "Playback through this device", select the device you want the sound to output simultaneously.
7. Click Ok on all windows and test.

Note: If the audio is low on the selected output, open the "Stereo Mix" properties again, select the "Levels" tab, and adjust the volume.

Feel free to ask back any questions.

I've used Stereo Mix several times to send audio to two devices simultaneously for event presentations. Stereo Mix never became the default output device.

To hear the microphone through the speakers, you will have to enable the "Listen to this device" feature on the microphone that will be used.

1. Press "Windows + R", type mmsys.cpl and press Enter;
2. Select the "Recording" tab;
3. Right-click on the microphone and select "Properties";
4. Select the "Listen" tab;
5. Tick "Listen to this device" and select the output device;
6. Click "Apply".

See if you can hear the microphone through the selected output device.

Set the computer's default output device to microphone audio output. The Stereo Mix should capture the audio from the microphone as well and should be output through the device chosen in the Stereo Mix settings.

Hi David, Thanks for continuing to help me on this.

Here is a screenshot of the sound settings. Notice that Stereo mix is the default device for recording, but what mic is it using? Also, Playback is set to Default (Lenovo's speakers) and yet it also went to PolySync20.

Here I'm just playing a video. The mixer is not installed. I did not realize that two sets of playbacks were possible. Is this because of the "Listen to" settings? Also, what is the difference between Default Device and Default Communications Device?

Sorry for asking so many questions. Thanks for all your help

Thank you David.

Does the "stereo mix" become the Default Device? Normally, I have my mixer (Behringer Flow 8) as the default device and it changes to "Ready."

What I'm trying to accomplish is all mic signals go to Zoom and to the venue's speakers, without feedback. And that all Zoom caller voices are heard through the venue's speakers as well

Here is a link to the Flow 8 just in case you wanted to know more. I'm using it in Streaming mode. https://www.youtube.com/watch?v=hE-igCVb3x0

Thank you again David. I appreciate you help.

Sorry. I didn't mention how to reduce microphone feedback in my previous reply.

To reduce this, you need to check your device driver settings. Usually, the driver comes with an audio manager, and in the microphone settings in the audio manager, you can enable "Echo cancellation".

The audio manager I'm referring to is usually found hidden in the system tray next to the clock.
