I am using the latest version of Windows 11 to record screen and system audio. However, when I start recording, the software does not pick up sound from the system, even though I have selected the correct output device in the settings.​

I have tried double checking the audio settings and making sure no other software is using the audio device, but the problem persists.​

Has anyone encountered a similar problem or have a solution to fix it?

Here are the troubleshooting steps:
- Right-click the speaker icon in the system tray.
- Select "Sound Settings".
- Scroll down to "More Sound Settings" (under "Advanced"). This will open the classic Sound Control Panel.
- Go to the "Recording" tab.
- Right-click any empty space and make sure "Show Disabled Devices" and "Show Disconnected Devices" are checked.
- Look for "Stereo Mix", "What U Hear" or a similar loopback device.
- If found, right-click it and select "Enable".
- Right-click again and select "Set as Default Device" (or "Set as Default Communication Device" if you want to check that too).
- In your screen recording software, now select "Stereo Mix" (or equivalent) as the input audio source.
- Check the recording.

You might want to double-check the "App volume and device preferences" in Sound settings and make sure the recording software has microphone/system audio permissions under Privacy & Security settings. Also, if you're using something like Xbox Game Bar or a third-party app, trying an alternative like OBS Studio could help isolate the problem. Hope you get it sorted soon—let us know if you find a fix!

Hey dismissevery,
Could you provide links to additional troubleshooting resources?

Select Sounds when you right-click the sound icon in the taskbar. Make sure that your output device is set to "default" on the "Playback" tab.

Hey, I’ve had a similar issue with screen recording software on Windows 11. It sounds like the system audio isn't being captured properly. One thing you could try is to check if the "Stereo Mix" option is enabled in your sound settings. Go to Sound Settings > Recording and make sure Stereo Mix is set as the default recording device. If that doesn’t work, you might want to try using a different screen recording tool, like OBS Studio, which tends to handle system audio better. Hope that helps!
