I messed up audio hdmi input, HELP! (vb-cable)

[RiquezJP]

I have a Sony A6000 + MIC connected via HDMI to a USB Video Capture stick - This set up has been working fine & correctly with OBS for audio & video over HDMI for about 6 months.

BUT - yesterday I decided to install VB-CABLE system plugin in an attempt to get OBS Audio Effects to output to Google Meet etc. (normally the hdmi/usb audio on Mac doesnt go through OBS without a virtual cable of some kind)
Anyway, this didnt work, so I removed the installation (vb-audio forum)

DELETE the VBCable.Driver file in your MAC/Library/Audio/Plug-Ins/HAL directory
DELETE the VB-CABLE Control Panel.app file in your Applications/VB-Audio directory

& restarted several times over by now,

However I now have a problem of NO AUDIO at all coming over the HDMI/USB device.
The standard Mic/Aux input that is part of the Video Capture source "USB Camera" is dead (no levels) & I cant work out what mistake I have made. I think everything was as before...

Can you help me troubleshoot this situation?

OBS Prefs > Audio > Global Audio : all disabled except Mic/Aux = USB Digital Audio
I am 100% certain this is the same as before & should be correct.

OBS Prefs > Audio > Advanced : Monitoring Device = Default

I haven't altered anything else, so I am at a loss how to return to the previous state.

I used Time Machine to recover my computer back to yesterday morning, before I installed VB Cable.
It took 7 hours & is a rather extreme step, but it fixed the issue. (restart, hold cmd+R)
I think its not OBS related at all, the plug-in did something to my system that the un-install does not reset. Without a roll back I might have never fixed that.
