This is a known issue we’re the settings keep resetting them self when using virtual audio devices. It may help using the default capture device instead of selecting the specific microphone.
If this still does not work, then I do not have a better solution for your right now.
I’ve brought this issue up again internally last week and hopefully we can get it fixed with an upcoming update, but at this time I can not promises that as we don’t have a 100% how-to for it, without using different audio equipment.
