hi all, just had a replacement hp pavillion entertainment laptop in exchange of an acer which i could connect to my yam amp via hdmi with no prob. this hp is a different prob, connected to amp via hdmi then to projector, when playing anything i only get stereo lights up on the amp. tried control panel-sounds and it has the digital output(hdmi) selected. cannot see any other icon to be able to select anything. i read somewhere that the laptop would auto see the amp and switch things accordingly, so maybe its only detecting the proj ?? got this posted in the laptop section also.
