MacOS – How to use Soundflower with El Capitan on the MacBook Air and hear the computer audio while recording with QuickTime

Okay, so I've tried so hard to set up Soundflower on my computer, and it doesn't seem to work no matter how many tutorials I watch. I'm running OSX El Capitan 10.11.4 on a MacBook Air 13-inch from early 2015. What I'd like to do is be able to record my computer audio, my microphone audio, and my screen at once, and hear my computer audio through my headphones.

Here's everything I've done so far.

I have the El Capitan Soundflower version. I can't post the link, because I don't have enough reputation points.

I went into Audio MIDI setup and made a Multi-Output Device, selecting Built-in Output and then Soundflower 2ch.

I also set up an Aggregate device, merging my Built-In Device (this is what my headphones show up as; they're Urbanear Plattan) with Soundflower 2ch.
enter image description here

I set my output to the Multi-Output Device, and my input to the Aggregate Device (system settings>sound>output/input).
Then, I went into QuickTime>file>new screen recording and set the input to Soundflower 2ch. I can't hear anything when I play my video back. Can anyone walk me through the correct process, or tell me what to change? It would be much appreciated.

Best Answer

This solves the problem: open Audio Midi Set Up (via search, or in Apps>Utilities) and on soundflower 2ch slide the master down to zero and back up to max for both input and output. Works fine now.
