I’ve used Audacity for many years. Just downloaded it to a new Windows laptop. Recording settings seem to be correct, but I’m only getting audio recorded on one of the two stereo channels.
Recording with a Focusrite Scarlett solo preamp. It works fine on the old machine.
In the Windows Sound Control panel, under the Recording tab, select your Focusrite, then Properties, then Advanced and check that the Default Format calls for 2 channels.
So you can try switching between MME and WASAPI. I have nothing further to offer, but it may be worth double-checking the available Default Formats in the Windows Audio Control Panel. Perhaps someone else has some ideas.
