Audio issues from Presonus Studio Live

[LabelleCC]

This might be a bit long, but I am totally lost. We are having an issue getting audio from our StudioLive console to FB Live. We stream our church services and it was setup and configured by a previous member and worked fine. This member is no longer and we have had issues with our Mac and it had to be replaced. Well now I have no idea how he got it to work.

What I do know is, that I can’t figure it out. We have three cameras that show up fine in OBS (connected via HDMI-USB adapters to the Mac) the main camera has also 2 XLR audio cables running to channel 13-14 on the mixer. From the Mac there is a headphone jack and a 1/8 cable running to a channel on the mixer as well for audio such has YouTube or iTunes.

The StudioLive console is connected to the Mac via USB. We have channel 13–14 which is for the live stream feed mapped to USB with in the routing for those channels in the console, I am sure it might be extremely easy and something is missing or obviously it’s not configured correctly. We called the previous member and he said that from what he remembers the audio capture output is supposed to be set for whichever USB adapter shows up for the main camera with the XLR cables.

I am very confused on why there are XLR cables coming for any cameras. And I am also confused on the input output configuration. I would assume all audio should go out from the mixer to the Mac via the console’s USB connection? OBS sees the mixer in the audio settings. I just know we are missing something.

Please forgive my ignorance, with all these pieces, I am very confused to say the least.

Any and all help or questions I might be able to answer is much appreciated.

Your confusion is completely understandable to me (as I'm not that far ahead of you)
As for why XLR from camera? is there a need for additional audio input? maybe background/attendee participation audio capture for remote attendees (ie not amplified to in-Sanctuary speakers, but distributed (cry room?)/streamed/recorded)??
So, XLS on cameras most likely unrelated to OBS/streaming. but just guessing obviously without knowing what every channel on the mixer is for, room setup, audio routing/config on mixer, etc. Presuming you have standard mics for people speaking and musicians, mic on camera seems an odd place to capture audio. Though, some folks run audio into cameras, so audio and video feed comes in on same HDMI to provide a time sync between the two...

Taking audio from OBS PC to route to mixer is not unexpected. Though playing copyrighted music in-house, and then livestreaming it is a good way to get that stream blocked (on public platforms like YouTube and FaceBook) by automated copyright systems.. but just a side note, as I presume this isn't a new setup.

As to your primary question

> I would assume all audio should go out from the mixer to the Mac via the console’s USB connection? OBS sees the mixer in the audio settings.​

The question is whether you want each individual channel on the physical mixer to be available on the streaming computer (so you can audio mix on that PC) or do the mixing on the physical mixer and take a mixed (sub) output from the mixer and send that to the OBS PC. Either is possible, each with its own Pro's and Con's
Now, are you running/using Presonus's Studio One DAW (digital audio workstation) software? You didn't mention Studio One, so I take it that it isn't installed on the OBS computer, right?

Sorry, here I'll have to defer to others, as my expertise is not MacOS. But typically, you need to install drivers on the computer to be able to decipher the USB data it receives. Have you installed Presonus Universal Control software/driver? I don't know if this is required or if there is a native ASIO driver that understands Presonus' USB transmission. That OBS sees the mixer is good, but..
My standard recommendation is to get audio and video inputs working outside OBS as a first troubleshooting step (ie, fresh OS boot, OBS not started). Make sure OS (operating system) permissions are set properly so OBS can access the various inputs. I recommend testing audio with native OS apps/tools. Only once that is working as desired, move onto OBS.

Just for reference, our HoW runs on a Windows PC, and I'd like to be able to mix the livestream audio separately on the OBS PC. But StudioOne is more complex, and lacking native audio output to local apps, so for now we are using an analog audio connection (sub-mix) from a StudioLive AR12c USB to OBS PC
