Multichannel flac playback fails, outputs only stereo. Need help.
wer:
I noticed that, but I focused more on:

so I thought you were concerned you settings weren't optimal. Or that the picture wasn't full resolution, or that it showed a 5.1 capable device when your receiver is a 7.2 channel unit, or something like that.
I'm surprised it reports "Dr HDMI" to the computer. Obviously this new version could not be more different from the older version I have, which is completely transparent except for doing what it's supposed to do: fix the EDID.
Blue mode 1 for yours I think is the best HD setting; but I thought your TV was 4k, which is why I said Green mode 1... Perhaps I was mistaken.

I thought you did understand this already. It's quite simple: The Yamaha is passing bad EDID to the Mac, indicating it can only receive 2-channel audio. The dingus strips out all the EDID, and replaces it with new EDID, based on whatever setting on the device you select. The modes on the device correspond to certain resolutions, audio channel capabilities, 3d capability, etc. When the Mac sees EDID that says "6 channel audio is supported" it happily sends 6-channel audio. Simple as that. If you selected a stereo mode on the device, it would trick your Mac right back into sending 2-channel audio only. So you need to make sure you pick a "5.1" or "Full Audio" mode, which is seems you already did.

Maybe. But another possibility is that the other options force (via EDID) your video card to think that the HDMI device doesn't support any video modes that are defined as valid in your Mac's video card configuration (refresh rate, interlaced, bit depth, etc). I don't know enough about Mac video configuration to say more.
Here's a test to perhaps help you decide which device to keep:
My old model keeps its configuration if it loses power. I have heard a mention that the new 4k model resets to defaults if it loses power. Since that would be a real drag, I would test that before you decide which one to keep, if you're saying you don't need the 4k.
Anyway, it sounds like you're getting a good image and all the sound channels you want, so it looks like your problem will be solved whichever device you keep. That's good.

Kept fiddling and finally got lucky I guess. Like to know WHY it's working now. Right now, with the Dr between the receiver and TV, the picture looks normal for the Mac and Cable TV, and the Mac OS and MC show show a 5.1-capable audio device "Dr HDMI" instead of "Samsung". I'd feel lots better, like I'd made more progress, if I understood why it's working and what it's doing. Seems to be working on a blue FHD setting. I'm puzzled why only 2 settings on that side even send a picture to my TV. Maybe need to wait longer & fiddle more when I change settings. I intend to post more if/when I know more.
Having second thoughts about returning the old version. I don't need the new model for 4k now, but might before long. Another concern was continued support (like firmware updates) because the older model is being discontinued. Don't seem like such good reasons now. Might try the other model before deciding which to keep.

I spent a good many hours trying to get multi channel working. I tried on an old Mac, a new Mac and a Linux Raspi 4. Couldn't do it. Although another poster has the exact setup as me (including the receiver model) got it to work. I couldn't do it....although I was using DLNA from the Mac to the Raspi and he was using the Raspi as the server. I later tried the Raspi all by itself and then I tried the Mac streaming to the receiver and bypassing the Linux. Eventually I gave up.
The sources I'm using are all showing 5 channels in MC. But they are being converted to 2 channel.
I got the original CD and played it using my CD player and the receiver spewed out beautiful 5.1 music.
Then I gave up.

Thanks for sharing. Your situation is not in any way similar to Scott's or what's being discussed in this thread though. Scott's issue is an HDMI EDID problem.
Dennis in FL:
I have a Marantz receiver with a Samsung TV and I'm using HDMI.
wer:
Scott has a Yamaha receiver, not Marantz. You just mentioned using DLNA, Scott's not. And you also talk in that thread about using a raspberry pi; Scott's not.
And you mention playing a CD with 5.1 channel music. CD supports only 2 channel audio. You either meant SACD, or you were playing a DTS-CD which is encoded 5.1 in a 2-channel package.
If you think you have the same problem as Scott, by all means try the solution I gave him, as it solved his problem. I didn't see any other point in your "Then I gave up." post other than wanting to share. Good luck with your issue.
