Playing Audio Through Multiple Outputs in Windows

To play audio through two devices at once, enable the "Stereo Mix" feature:

1. Right-click the speaker icon in the taskbar and select Open Sound settings.
2. Scroll down and click on More sound settings under the Advanced section.
3. In the Recording tab, right-click and select Show Disabled Devices.
4. Right-click on Stereo Mix and choose Enable.
5. Set Stereo Mix as the default recording device by right-clicking it and selecting Set as Default Device.

This setup allows audio to be duplicated across multiple output devices.

After enabling Stereo Mix, configure your playback devices:

1. In the Playback tab of the Sound Control Panel, right-click your primary audio device and select Properties.
2. Navigate to the Listen tab.
3. Check the box labeled Listen to this device.
4. From the dropdown menu, select Stereo Mix as the playback device.
5. Click Apply to confirm the changes.

This configuration routes audio through both selected devices simultaneously.
