Recording - mac 10.13.3 with audacity 2.2.2

I updated my MBP (a late 2016 model) a couple of months ago and updated to Audacity 2.2.2 around the same time. Since then I have not been able to record a thing.
I’ve been using audacity for a good few years to record mixes through a Native Instruments ‘Traktor Audio 6 interface’ and it has work like a dream. Literally plug and play.
I have spent days now trying to resolve this but without success. I’ve even tried soundflower as a work around. That doesn’t work either.
Audacity is seeing my audio interface as usual. (I usually set it as my input and output source), start monitoring and all is good. The only thing left I can think of is perhaps it could be the adapters I am using for USB-C ports for my new mac, but it is seeing the interface in the drop down menus.
Any help or ideas would be much appreciated.

Apple (upper left) > System Preferences > Sound.

You should be able to see your connection or interface in the list and if you select it, you should see the bouncing ball sound meter move. While you’re in there, make sure the volume sliders are all turned up.

Audacity gets sound from the computer, not the device, so this has to work before anything else happens.


Followed what you said, except I don’t have the option to turn the sliders up because its telling me ‘the selected device has no output/input controls’


Some USB connections don’t have controls. The import point is getting the bouncing sound meters when you perform. Do you?


Bouncing sound meters. (click the graphic to see the whole thing).

Updated the MBP how?
What are these USB-C adapters you speak of?
All that said, it is very strange for Audacity to not see audio when the Mac does.
