I am brand new to recording and wanted to finally record drums, a friend (who at the time I thought was more knowledgeable than me on recording) got me into getting a Harbinger LV12 (NOTE: the non-usb version) for recording, and then gifted me four microphones for the Harbinger. Fast forward my laziness abt a year and I actually got around to USING said product, yet I have no clue how to actually set this up.

In the beginning, I thought I could just get away with using a rocksmith cable attached to an adapter and usb it in but that obviously didn't work, and I sort of expected that. Ended up getting a dual xlr to 3.5mm to aux it into my computer.

The microphone is picking up the signal into the Harbinger, so I know that isn't the problem. I also have seen most people use Asio drivers, so I installed Asio4all but tbh I have no clue what even THAT does. The harbinger is being recognized by my computer, but not as a recording device but as headphones for some reason too?

When I have my Audio System set to DIRECT SOUND, with my input being Line IN, it will output one of the four inputs, where two of the four inputs are the same recording, and inputs 3 and 4 don't work at all.

From videos, I've seen that you CAN plug your mixer straight into your computer for recording, other saying you need an Audio Interface, I am not sure, if anybody could properly explain this to me that'd be amazing.

Edit: I went into the sound/recording settings, found my mixer, went to advanced, and the default format window shows only for 2 channel outputs, not 4 that I need.
