Help with Separate Volume Control for Mic and Desktop Audio in OBS

[Eirokas]

Hello,


I'm facing an issue where my mic volume is being routed to the same channel as the desktop audio in OBS. I want to control the mic volume and desktop audio separately. However, when I go to the Audio Settings, I can only select the Audio Interface, not the mic itself (see attached picture - Audio Settings). The same happens when I try to add a source using Audio Input Capture (see attached picture - Audio Input Capture).


I'm not sure if the issue is that my mic, which is connected to my Scarlett 2i2, isn't showing up or if it's a routing problem.


For reference, here are some additional details:

• My Audio MIDI setup (see attached picture - Audio MIDI).
• My input and output device is the Scarlett 2i2 4th Gen (see attached pictures - Input, Output).

Any help would be greatly appreciated!


Thank you!

The device selection in OBS, figures out INs and OUTs already. It's not mixing there.

Some physical interfaces have a loopback switch, that sends what it gets from the computer, back to the computer. I have no idea why that switch even exists, because every computer operating system that I know of can do that natively (it's how the Desktop and Output Captures work), but it's there, and might be your problem.

Beyond that:

• If you have open-air speakers, they might be getting into the mic through the air. People tend to forget that air is just as valid a signal path as anything else, and can't be turned off. So you just have to manage it. Mostly don't feed it what you don't want it to have...
• You might have the OS set to pass the mic through to the speakers. Windows calls it "Listen to this device", and it's buried in the Properties for each input. Mac might have something similar. If it's on, then OBS would pick up the mic from there.
• Similar to the previous point, OBS's Monitor also gets picked up by the Desktop and Output Capture sources, if they're set to the same device. So if you Monitor something to your headphones or speakers, and capture the same headphones or speakers, then you get another copy of what was Monitored.
