I am having a problem with the sound from the TV, there is none. Most of my audio comes from my Samsung HTiB and never use the TV speakers. I got the Harmony 880 recently and was going through the settings when I realized this.
The Set top/cable box isn't set to mute, so that's not it. The volume controls on the set top/cable box will go up and down but still no sound even at full and the TV at full.
Optical cable connecting cable box to HTiB (shouldn't matter). Component cables from the TV into the cable box, and HDMI 1 connecting to the HTiB for DVD's. Sound is fine coming through the HTiB, but no sound from the TV set itself. I thought maybe the HDMI cable is interfering somehow but it's the same even when I disconnect it from the TV.
In the set up menu under sound everything appears to be normal, internal mute is off, mode is set to movie, SRS Trusurround is On.
At a loss, any ideas?
