Hi Shashank Jaganntha
Welcome to the Microsoft Community
Understanding your problem , the volume of USB headsets is too low in the 24H2 version
If the volume of your USB headset is too low after updating to Windows 24H2, you can try the following steps:
Uninstall and reinstall the driver
I noticed that you mentioned it in the link you provided, please ignore it if you have already done it
Open the device manager, find your USB headset, right-click to uninstall the device and check Uninstall the driver. Restart the computer to automatically download the device driver
Check the application settings:
Some applications have their own volume control. Check the settings of the application you are using to make sure the volume is not set too low.
Adjust the audio output format:
The audio format output may affect compatibility.
Right-click the speaker icon on the taskbar and select "Sound".
Select your device and then click "Properties".
Under the "Advanced" tab, you can select a different default format (such as 16-bit, 44.1 kHz or 24-bit, 96 kHz).
Try different settings to see if you can increase the volume.
Contact me if you need anything else.
