AudioCapture[] not capturing sound from my Focusrite input

Windows 10:

$AudioInputDevices
{"Focusrite USB (Focusrite USB Au", "Microphone (B525 HD Webcam)"}

In windows settings I can see that the "test your microphone" line is reacting to my input through the Focusrite USB and

AudioCapture[AudioInputDevice -> $AudioInputDevices[[1]]]

returns the appropriate recording box but is unresponsive to Focusrite input.
