Thanks, myoda. Yes, I read that on the Cisco manual. I can get analog audio from the left/right outputs of the box and connect them to the single audio input on the Sharp associated with HDMI 1 and then selecting “HDMI + Analog” in the Sharp, but I was looking for a working digital audio input. There is no other digital input in the SHARP 80 but the HDMI Linear PCM. Maybe passing the signal through an AVR will be different. The odd thing is that the TV plays audio right for a few seconds through the HDMI connection and then goes silent permanently with the message of incompatibility…Originally Posted by myoda 
I am assuming that you have an hdmi cable attached directly to an hdmi input of you televison. Try this:

Important Notes Regarding the HDMI Interface on the Set-Top
The HDMI interface automatically confi gures the audio output for a format supported by the television. Because not all
TVs support the Dolby Digital input, the HDMI interface may automatically select a 2-channel stereo audio confi guration
instead of Dolby Digital, which it carries over to the other digital audio outputs of the set-top. This prevents your home
theater system or Dolby Digital decoder from providing the full Dolby Digital surround-sound effect.
You can override this confi guration by completing the following steps.
1. Press SETTINGS twice on the remote control to open the General Settings menu.
2. Press MOVE UP or MOVE DOWN to select the option Audio: Digital Out.
3. Press MOVE RIGHT to select Dolby Digital. This setting will send Dolby Digital audio to the HDMI, DIGITAL AUDIO
OUT, and OPTICAL AUDIO OUT connectors on the set-top.
