HDMI channel mapping

Origin
1

When using the HDMI interface my Denon AVC-X4700H always shows that all channels are in use. If I configure stereo mode only in Audirvana there is no effect. Always all channels are used. That’s a problem because when hearing stereo music, my receiver is configured not to use my sub woofer. But I never get stereo from Audirvana.
In other words: When switching to stereo output in Audirvana only two channels should be enabled. The same as when switching to two channels in macOS Audio-Midi-Setup - this works.
Following the info from Audirvana for both cases.

Another issue I haven’t had with Audirvana 3.5.50 is that when I map channel 1 and 2 to my 7.1 back surround speakers (Configure speakers in Audio-Midi-Setup and without the stereo option in Audirvana) I was able to hear stereo music with them. With Audirvana Origin there is no sound from my back surround speakers. Please see the third log from Audirvana.

Hello @sbmn,

So you mean that when you are in this configuration you do not hear your music in Stereo?

Hello Antoine,

in this configuration I can hear stereo. The problem is that my AV receiver has all channels active.
It is different when I switch to 2 channels in the Audio-Midi-Setup tool. Then the receiver has only two channels active.

Another effect: When I switch to 8 channels in the Audio-Midi-Setup before starting Audirvana, Audirvana shows 7.1 channels in its configuration. When then playing anything in Audirvana (could be also stereo) it shows 8.0 channels in its configuration. I don’t know if this is a useful information for you.

In this configuration I cannot hear anything when my surround back speakers are configured as 1 and 2 in Audio-Midi-Setup. Their default configuration is 7 and 8.

Regards

Swen
