Bigbox: laptop connected to tv sound issues

[Teusan]

Hi, 

I have this Bigbox behaviour that bothers me: my laptop is connected to my tv through hdmi, videos are ok, sound is played through tv speakers but the transition effects sound are coming through laptop's speakers, like attract mode or when I'm navigating in the menus.

In the Windows audio control panel, disable all audio devices except HDMI. Windows will no longer attempt to use the laptop audio devices.
