The problem is that when I have my cable box as a source, and I hold the source button down and then select an alternate audio source (CD), I lose the video image from the cable box. The unit works fine when I select the Cambridge video and then choose my cable box for audio. I only seem to have trouble with HDMI audio.
I've changed the settings multiple times, restored factory defaults and started over, etc., but I can't solve the problem and tech support is stumped.
Does anyone have any ideas? I had an AVM-20 for years and had no issues, and the only reason for the updgrade to the AVM-50 was to get HDMI and room correction, and now I'm having issues.
If I understand correctly what you are trying to do is listen to HDMI audio from source "A" while simultaneously watching Component video from source "B".
I don't think the hardware can do that.
HDMI audio is not a separate signal. It is embedded in the blanking intervals of the HDMI video signal. Even when you are playing non-video content from, say, a CD, the HDMI audio is embedded in a video signal of SOME sort -- even if the player is just putting out a black screen.
Now, what this means is that the Anthem has to "process" the HDMI video to extract the audio. In terms of Setup, that means sending the HDMI input to the Scaler (the line near the top of the Source definition).
But there's only one Scaler and you've got the Component video going through it from your cable box.
So that HDMI from the CD player is not being processed, and thus its audio is not available for split-source playback.
To put it another way, you can watch HDMI video with its own audio or with any other NON-HDMI audio. And you can watch non-HDMI video with any NON-HDMI audio. But you can't listen to HDMI audio combined with any video but the video coming in on that same HDMI cable.
Now, what I would expect to happen is that your Component video would continue playing but you would not hear the HDMI audio you selected to accompany it.
Instead, as I understand, you are saying that you loser the Component video. You didn't mention, but do you get the HDMI audio or does it stay silent as well? That may be a bug in the firmware, but the bottom line is notwithstanding that, I don't believe you can do what you want to do.
HOWEVER, if you wire up an alternate audio path from the CD player, and define a Source which uses that for audio, then you CAN combine Component from the cable box with that other, non-HDMI audio.
In the case of a CD player, likely choices would be to wire either a Stereo Analog pair or to wire Optical or Coax Digital audio. In the case of a CD the digital audio carried by HDMI is identical to what's available on Optical or Coax, so that would be the closest match to what you are trying to do now.
One thing you'd need to check is whether your CD player produces output on *BOTH* HDMI and Optical/Coax while playing a CD. If so, then there's no hassle. Wire, say, Optical as well as the existing HDMI. Set one of your Source definitions to listen for audio on that Optical instead of the HDMI from the CD player. Select Component video from your cable box as you are doing now, and then select your new Source to combine that with Optical Digital audio from your CD player.
