Hello, I have an acer aspire 5810tz laptop. When I play movies from it directly to the tv through the hdmi cable the sound goes thru. When I connect the laptop to my onkio receiver only the picture goes through and not the sound. I switched the receiver to get the sound from the hdmi source. Help!
Could be your Onkyo receiver is not HDCP compliant. What make and model of TV and Onkyo do you have?
