Question: I've connected the HDMI? output on my DVD player, set-top box or other source device to one of the receiver's HDMI inputs, and I've connected the receiver's HDMI output to an input on my video display or TV. Although I am able to see the picture on the display and I can hear audio through the TV's speakers, why can't I hear any audio through the speakers connected to the receiver, even when I disable the TV's speakers?
Answer: Your receiver is capable of switching HDMI signals, but it cannot access the data and process it. Thus, the receiver is passing the audio and video information through to your video display without processing it in any way.
