m15 R1, Alienware Mobile Connect, cannot hear caller

I have weird trouble, installed the newest Alienware Mobile Connect drivers, installed the newest Alienware Mobile Connect app, all works fine until a make call or get a call. The caller is able to hear me so MIC works fine but I have no sound out of the laptop can't hear anything caller is talking to me. Apart from this no problems with sound at all. All other apps sound output works fine.
