Audacity won't play or record

[mac_audio]

I am learning to do voiceovers and also learning new gear.

I have an Onyx Blackjack audio interface, and when i change mics or cables, I usually just unplug the audio interface since it doesn't have an on/off switch, and I don't want to damage my mic with a sudden power surge.

Just now I recorded on track in Audacity, but haven't saved it yet. I unplugged my Onyx, changed mic cables, plugged back in the Onyx, and when I hit Record I get an error pop-up:

Code: Select all

Error opening sound device.
Try changing the audio host, recording device and the project sample rate.

Why am I getting this error?

I have macOS Sierra and Audacity v2.2.2

Never had this issue on my old Mac and with older version of Audacity.

If I quit out of Auacity and come back in, the problem disappears, but what is annoying is that often I have unsaved work that I do NOT want to save while I am swapping out mics and cables, and so to resolve this it forces me to save any scratch work which is a pain!

Changing cables in the middle of a production or recording is insanely dangerous. You should only hot-swap cables when the production isn't that important.

If Audacity does survive the changeover, Transport > Rescan...

Why is it "insanely dangerous"?

And what do you mean by "hot-swap"? (I had "Take 1" recorded, but not saved, unplugged my audio interface, plugged in a new cable/mic, plugged back in my audio interface, and went to Audacity > File > New to do "Take 2" when I get the error mentioend above.)

I didn't save "Take 1" - and would prefer not to - because maybe "Take 2" is superior and I will save "Take 2" really as filename ""Take 1". (I'm just experimenting and getting comfortable with Audacity and my gear...)

If Audacity does survive the changeover, Transport > Rescan...

What does that do?

And why is this error appearing in the first place?
