I'm trying to pass output from a Cox Contour cable box through my SP3 to a NAD M22 amp via balanced output. I tried HDMI in with the hope of audio and video out, but the SP3 displays HDMI In No with neither audio nor video. This even though HDMI from the cable box to the projector results in video, and Cox labels that HDMI as input for a TV, suggesting it carries both audio and video. I tried analog audio from the cable box to the SP3, but the SP3 display shows nothing and there is no audio. This even though analog audio to the Audio Engine 2+ results in sound. Am I over looking something? The manual is long but not explicit on procedure, e.g., does it matter which HDMI input is used and how do you select it?
I send HDMI from an Ayre DX-5 DSD disc player to the SP3 for surround, and balanced front LR analog from the SP3 to a by-pass input of an Ayre KX-5 Twenty preamp. The resulting audio is nearly as good as stereo direct from the DX-5 to the KX-5. Proof my SP3 can process HDMI.
