If you are experiencing sound issues after Windows Upgrade, here are some troubleshooting steps that you can use to check and see if they would sort the issue out.

First, please check if the volume wheel is properly set up.

1. Go to the Sound settings and choose Sound Control Panel, located on the top right size of the screen.

2. Under Playback tab, right-click on an empty space and "Show Disabled Devices". Locate "Sound Control Panel" on the top right. 

3. Find the disabled device and re-enable it. This might be the connector for the React headset, and then disable any other devices.

Make sure that the microphone is securely plugged into the headset and that it goes upward to the base of the headset, we always recommend that the microphone arm is pointing up.

We would also suggest that you test out the headset on another PC, with and without the 2-meter extension cable. 

Windows 11 treats the headset like one device, on Windows 10 you had separate outputs for the microphone and the headset and this is issues with the low sound/echo/microphone can happen.

What you can try and do is to turn off the headset in the recording tab.

Enable “Enhance Audio” on Windows 11

This is the first and foremost setting that you must enable on Windows 11 and check if this serves your purpose. Turning this feature On will automatically boost the sound quality on your device. Here’s how you may enable “Enhance audio” on Windows 11.

2. Click System > Sound (right pane).

3. Scroll below and click over the option – “All sound devices” under Advanced.

4. Click Speakers inside Output devices.

Enable Spatial Sound in Windows 11

Spatial sound is basically an audio format that provides an immersive audio experience over headphones (wired or Bluetooth) or external speakers.

In the case of an external speaker, it feels like the sound is coming from all corners as opposed to previously coming from the speaker itself. Similarly, if you enable Spatial sound over a headphone, this too improves the sound quality to a larger extent. 

Though you may enable spatial sound on any headphone or speaker, it works best only on the supported devices. 

Note: To turn On this feature on Windows 11, you need to first connect a headphone/speaker to your device.

1. Right-click over the Windows icon and select Settings.

2. Click System and then Sound.

3. On the right pane, you may find two options to choose from. 

4. Click over the option – “Headphones”.

5. Scroll down to “Spatial Sound” and use the drop-down menu to select “Windows Sonic for Headphones”.

This setting won’t work if you have enabled the Mono audio on your PC. So, disable mono audio first then only you may turn the spatial sound in Windows 11.

Turn On Mono Audio in Windows 11.

Another important feature that can help to improve the sound quality in Windows 11 is the usage of mono audio. When one enables this setting, the system combines the left and right audio channels to provide a single sound.

1. Open the Settings page by pressing Win + I.

2. Click System and then Sound on the right pane.

3. Look for a setting “Mono audio” under the Output section.

4. When found, slide its toggle switch to the right.
