Choosing other audio source doesn't work

Had mixer for a while. Cant switch between audio sources at all. Even reinstalling and updating the Jax core. Any suggestion with debugging, or settings not enabled for Rainmeter, or Jax core?

Bumping this. Identical issue, identical selection (Speakers - Realtek(R) Audio), can't switch.
