Question / Help OBS only hearing two mics from Mixer, three mics plugged in.

[LeftRightGoodnight]

Hey guys, just downloaded OBS (Windows 7) and I'm using it to locally record (not stream) a podcast using a HD webcam, and three XLR mics plugged in through a mixer. The video portion is working perfectly. Audio-wise, I can only hear two of the three mics that we are using.

I'm using a mixer (M-TRACK Quad) with three XLR mics plugged into it, with the mixer itself connected to my computer via USB. If I record audio using a program like Adobe Audition, it can hear all three of the mics I'm using, but when I record using OBS only the first two microphones can be heard in the recording.

I've gone through all the settings and can't figure out any reason as to why this is happening, any help would be INCREDIBLY appreciated!

Maybe try this idea instead....

Use a digital audio workstation (DAW) like Ableton Live Lite. Let Ableton handle the mics through the M-Audio ASIO driver. Create three separate audio tracks in Ableton associated with each mic. Send their outputs to Master. Wherever Master goes, use that as in an input to an OBS Studio audio input capture device.

Thanks so much for the suggestion!

I've downloaded the program, got three seperate tracks, and sent their outputs to master. I'm not sure what you mean by "wherever Master goes" though... there's no way for me to set Ableton as an audio input capture device in OBS?

Thanks again for trying to help me out I really appreciate it

Master track normally goes to studio monitors.

In your case, you got your speakers setup so that they go to Output 1/2 on the back of your mixer. Your mixer likely uses its own USB audio driver or has an ASIO driver.
In Ableton, there is a Audio type dropdown with probably ASIO, MME/DirectX available.
Fiddle with both of those settings and match the output device with a Audio Input Capture source for your scene.

The idea here is to use the DAW to handle all three mic inputs and aggregate all three into one sound, then route that sound to the master. The master is captured by OBS Studio on output of the audio device as audio input capture to OBS. Whatever OBS can see as an audio capture input device, you need to send the output to from Ableton Live.

Hope that makes sense..

P.S. I have FocusRite Scarlett with multi XLR ports and this works. Its the same idea.

I have the same problem and can't resolve this issue. I'm on a MAC and OBS only hears 2 out of my 3 mics. ECAMM hears all 3 so it must be an OBS issue. Thoughts? Thank you.

A lightweight alternative to a fully blown DAW software package would be the VST host Live Professor. Requires ASIO support but you can load a VST mixer and just run that module, freeing your CPU up by not having to run an entire DAW.

I had issues with multiple sources and had to enable ASIO support in OBS of my MOTU828, and that was a bit of work, but once set up it works treat.
