Internal Audio Not Recording On Mac

I used to be able to record zoom meetings by capturing the audio of my microphone AND internal audio of my mac so that I can hear participants when playing back the recordings.

However, since my Mac updated, it has stopped doing that. I have some audio settings in place on my Mac from MIDI Setup which allows me to record both internal and external audio. Works fine on other software such as Loom and Quicktime so I know the problem lies within Zoom audio settings somewhere.

I've tried nearly every combination of audio settings but still no luck.

It would be much easier to explain on a screen share.

Please can someone help me with this!

Thanks in advance,

Evan.
