I have the UAudio Volt 2 two channel USB interface (https://www.uaudio.com/audio-interfaces/volt-2-usb.html). Both channels can be used with the Ableton product. However, OBS doesn't receive channel 2. Channel 1 works as expected. The audio mixer doesn't show any signal from Channel 2. It appears the USB interface drops channel 2.

If you only have one microphone, then that's normal. You need to configure obs for single channel input https://audiouniversityonline.com/recording-to-one-side/
Hi,
I'm responding to this because it came up in my search for the same problem. I figured out a "fix", but not sure if it's intentional or not.
It's also in Streamlabs OBS, so I'm not sure how much help it'll be here :)
In Streamlabs OBS under your audio properties, there is an option to "Downmix to Mono". That got my mic audio coming through both sides. I did the same in Adobe Audition and it worked like a charm.
It seems like Windows (or UA? not really sure) wants to treat the two inputs on the device as one single input, obviously a left and a right side.
Almost everything I looked into told me to refer to UA's software but none of that helped. I'm going to continue searching for a legitimate fix for this but for now, hopefully this helps someone.

Normal OBS has that too.
In terms of processing order, the Mono checkbox comes after the Pan/Balance control. That's backwards compared to pretty much every professional thing, and means that you're forced to have the mono thing centered no matter what. But it also means that you can have two copies of that same source, Mono both, and Pan/Balance them hard left and right, to end up with effectively two independent inputs, both centered. That *only* works with 2-channel interfaces though, since the pan/balance control is stereo only.
By the way, SLOBS is technically an IP violation, for using the name "OBS". If they called it something else, it'd be okay, but the purpose of forbidding the name is to prevent the very confusion that they cause.
It's actually OBS that does that. It's even worse for many-channel interfaces that it also insists are one single source of surround sound. So it downmixes that to stereo or whatever OBS is set for, and THEN gives you the mess that it made of your band or conference mics or whatever, to try and salvage something from. Not good.
This post in the Mac forum suggests that OBS is finally fixing that, but it might be a while before it gets to everyone:
Cant record DAW audio and MIC at the same time
Hi! I have an Orion 32 plus, Pro Tools, OBS, and I can't reach OBS with a microphone and the main out, both at the same time. It looks like OBS is able to only receive audio from outputs 1 and 2, but I don't know if Im wrong or missing something. Thank you very much in advance to any comment or...
