The new Mac mini sees "through" my A/V Receiver and only wants to send audio to my TV. I want the HDMI Audio to go to the A/V receiver, and let the receiver pass the video fro the Mac to my TV.

Thanks for the reply. I tried all the settings possible on the Samsung receiver. The "audio assign" settings allow for HDMI, COAX, or Optical, and it's set for "HDMI" as it should be.

The older 2012 Mac mini recognized the Samsung for audio, and understood the monitor was the big SONY TV. This new-er (late 2014) Mac mini indicates a connection only to the SONY TV in both the audio and the monitor/video settings while looking at the Preferences screen. It's like it sees through the receiver. If I can't find a setting I'm missing, I'll just probably run a straight cable to the TV's other HDMI input, and listen to the Mac mini audio with the receiver set to "TV" using the HDMI ARC function of the receiver. I didn't want to filter the audio through my TV, but it'll have to do. :-/

It just occurred to me. On the old Mac mini, when I was using the HDMI audio for the first time, the Samsung receiver didn't decode the audio properly because the Samsung wanted to do the decoding and separate the audio into the appropriate channels, not the source (the Mac mini).

I had to reconfigure the HDMI Audio on the 2012 Mac mini to send 2ch STEREO to the receiver, so the receiver could decode whatever Dolby surround signal was embedded onto the stereo track.

This new Mac Mini appears not to have a command to open/edit that setting. I can't find any HDMI Audio config screen on the late 2014 Mac mini searching the HELP file for O/S 12-Monterrey. (sigh)

Samsung HW-D7000.

Nothing has changed on the SAMSUNG settings. The only thing that's different is I swapped out an older Mac mini for this late-2014 model with a different O/S.
