No 'audio monitor' Filter Option on Pack108.dmg

[WanWaniels]

Hi there, I had OBS set up and running on my old (intel) mac working fine the way I wanted it to.

Now on a Macbook Air M2, I have installed VBCable_MACDriver_Pack108 and am missing the "audio monitor" in filters for my mic

Is there a way I can get this back please?

Thanks for any help
