Did you set the default audio output device to the HDMI output?
Previously I had a Vista OS HP machine which I utilized to view dvd movies on my flat screen. I used a HDMI
cable to make the connection...everything was good.
I now have a HP win7 machine and did the same thing
the movie or video displays ok but there is no sound
What's up with that? Don't understand why anything would
be different. Any solution would be greatly appreciated.
