Error opening sound device

I’m brand new to Audacity and I’m editing my first podcast.
I spent several hours cleaning up the file last night then Audacity froze up.

It gives me this error message:

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

How can I get it to work again?

How long is the show?

Did you connect or disconnect anything just before it failed?

Did you take or make a Skype call right about then?

This is the manual listing for your error.

I don’t think this is it, but I can see one mismatch. You have the Mac microphone set to record mono and yet you have a stereo (two blue waves) show.

It’s good practice to export all your original sound and performances as WAV 16-bit, 44100 sound files before you start editing and edit a copy. Saving an Audacity Project is not recommended for this.

If you’re cutting your original performance and Audacity goes into the mud, it might take the original recording with it.


Which version of Audacity are you using? (Look in “Audacity menu > About Audacity”.)
