Cisco CIS330 use HDMI and Digital Optical Audio?

I just got Telus Optik (IPTV) and it uses a Cisco CIS330 for the set top box. I have the video going out via HDMI and I need the audio via Digital Optical. I can't see how to set that properly via the Menu (I'm on hold w/ tech. support right now).

Anyone know how?

If I hear back from tech. support I'll update with the solution.

OK, I suck. This device outputs to all ports at the same time. User error.
