When i put my headset in i can hear a very low sound.
This would mean that the driver is ok and possibly the sound volume needs to be increased…
Go to:
1) Control Panel -> Sounds, Speech, and Audio Devices section
2) Choose Sounds and Audio Devices
3) Now Sounds and Audio Devices panel will appear.
4) In the Sound Playback section click on the Volume
5) In Volume Control panel set all controls to max volume (up)
