Audio clicking echo noise

Hi friends. I have a strange problem with my new alienware 17 r4 laptop. After installing windows 10 and update realtek audio driver , the load annoying clicking echo sound come from the right corner of my laptop with every sound. More stranger is the noise produced even if I mute my sound. Deleting realtek audio driver and installing basic audio driver remove the noise. Can any one please help me about this? Is this an hardware problem duo to subwoofer? Another thing is my right speaker is loader than left, is it beacuse of subwoofer in the right side?

 

I found it in YouTube, similar sound whenever starting music the sound that disappear few seconds later if I mute it.
