So is HDMI the default audio device, or alternately did you set whatever program you're using to the HDMI audio output?
I connected my HP Tower to my LG 42" LCD TV (Hi-Def). I'm able to view all aspects of the tower. However I cannot get any sound from the TV. I tried disconnecting the external Logitech speakers I have hooked up to it. I also tried to disconnect and reconnect the HDMI cable to the CPU and still no sound. I also went to sound device settings and it does show the HDMI as the choice for sound. Help!! Where am I going wrong?
By the way the TV works fine and I do get audio from the TV.
