pwcrofton,
Have you checked to make sure that your audio isn't muted in the television? There are two ways - one with the remote (that causes a speaker icon to come up), and the other is inside of the menu.
Keep me posted.

I have a 32" LCD LNS3251D and installed DirecTV wiuth an HD receiver with HDMI. I am able to get a great picture, but absolutely no audio. I tried connecting a DVD player to the LCD with HDMI and have the same issue. I have tried different HDMI cables on both ports and still nothing. I called 800-SAMSUNG and the only suggestion they had was to make sure the audio on the DirecTV box is set to PCM and not Dolby (checked that and it came as set to PCM by default). I do not see any firmware available on the Samsung site for this model. I am able to receive video+audio fine with the RGB cables, but obviously not HD. Any suggestions for HDMI and this Samsun LCD TV????
