Question

Not a question at all this is an instructional guide on how to get this done with a Mac OS. I posted this as an answer to someone in another post but felt like this could be shared to everyone.

I have a 7.1 mixing setup on the StudioLive 32S Series 3 using ProTools Ultimate. My computer is a Mac Studio M1 Base. I am using the AVB method for audio.

Connections:

1. An ethernet cable from the Mac Studio to the AVB port on the SL32S (You need to use WiFi to get internet since the ethernet port on the Studio is using the SL32S for DNS).
2. An ethernet cable from the internet port on the SL32S for connection to you LAN and the internet.
3. Using Mix outputs for feeding sound to the speakers (You need to stereo link Mix 1/2,5/6,7/8):
   • Mix 1/2 = Front Left & Right
   • Mix 3 = Center
   • Mix 4 = LFE/Sub (Use DAW EQ in your mix to kill the frequencies so LFE sound is only heard)
   • Mix 5/6 = Left & Right Side Surround
   • Mix 7/8 = Left & Right Rear Surround
4. Click on the Mix/FX Button on the SL32S and select the network symbol for each mix outputs input source (You also need to select the AVB channel you want to feed into the Mix output, "AVB 1/2 to Mix Output 1/2". You can also do all of this routing in the Digital Patching Menu utilizing the control app for the console.
5. FOR THE APPLE OS SIDE OF THINGS:
6. Go into the App Launcher and open the Utility's icon then select "Audio MIDI Setup"
7. Click on the the SL32S name, (It will be called "Studio Live 32S: Audio Unit 0")
8. Under both "Input" and "Output" tabs, select the first stream ("Channel 1+Channel 2+", etc...)
9. On the bottom right hand side of the window, select "Configure Speakers" 
10. Configure your speakers as follows:

Doing this will allow you to play back 7.1 Surround Sound stems from QuickTime as the Music app won't play them back. All other audio like web browser and such will playback on Stereo only using Mix Output 1/2. 

This audio setup will work in any DAW. I have also been able to setup the Dolby Atmos Renderer to work with this setup, have not completed the objects mapping.
