If you plug in the device first and then start Audacity, Audacity should see it. Does it?
Yes, how about that!
Indeed, sometimes Audacity does see the io2 if I already had it plugged in, and hadn’t run Audacity before (since reboot).
In that case the device info reported is as follows.

When I try recording with the io2, it seems to play back at a lower pitch. This is the case when I select either “io2: Front Mic:0” or “io|2: USB Audio (hw:2,0): Front Mic:0” as the input. It appears that it is recording at 48kHz even though my project rate (and track rate) are 44.1kHz. (If I change the track rate to 48kHz after recording, the pitch is corrected). This is puzzling because the “io2” and “io|2” devices both support 44.1kHz (as well as 48kHz). Though the 44.1 vs 48 problem seems more common:
and perhaps more work-aroundable (I might consider changing my project to 48kHz… but not 4kHz).
Do any of these observations shed any light on the issue I was having with sound input from the built-in device?
