Unfortunately my screen doesn’t look quite like the given screenprint so it’s a little confusing (no labels) but I figured it out and it works.
This appears to be a new feature on a new version… As a longtime Audacity user, it would have helped that such a major feature / possible problem was highlighted somehow (rather than possibly buried deep in documentaton) - could have saved a lot of other troubleshooting. That suggestion made, I’m grateful the software is free and for those who donate time to make the updates and documentation. Thank you
Not a new feature, the device toolbar has been there for several years (all of the 2.x series and many earlier versions).
There’s a picture of the main Audacity window on the first page of the manual, and it is “clickable”. http://manual.audacityteam.org/o/index.html#reference
The manual is also available in the Audacity Help menu (if you use the recommended Windows “installer” version).
