My notebook is

Asus P53E - core i5
Windows 7 installed

Audio from PC speakers and headphone is distorted when i turn on bluetooth or some usb device plugged in. I belive this is a software issue. I tried updating my audio drivers but nothing help. Any help will be appreciated.

Update: After a few days digging I found that this problem is causing by the asus sound enhancement application SonicFocus. The distortion stops while turning off sonic focus. Can anyone help me with a solution other than turning off SonicFocus

And now I have got a solution for my problem. I'm posting it as answer if someone else is having the same. I just disabled All Sound Effects from Speaker Properties. There's no distorted sound while turning Sonic Focus on or using BlueTooth. enter image description here
