USB Audio option not always available

I have to set preferences for Devices every time I start Audacity. The problem is, the option for ‘USB Audio Controller’ is not always available. Some time it appears, most times it doesn’t, although all the required plugins have been successfully installed. I have Audacity 2.0 under Windows 7 Professional. Any help will be greatly appreciated.

The USB device has to be plugged in and perfectly working before you open Audacity. If you get the order wrong, you can have a perfectly working USB device and it will be invisible to Audacity.

You can force Audacity to look for USB devices after the fact with Transport > Rescan…

You can get serious technical insanity with an erratic or broken USB connection.


I would recommend you upgrade to the latest Audacity version from
