Audio Devices and Channels

I have a different device for handling mic input and voice output.
And all would be well, except the notifications sometimes sometimes on a third device (I have 4 audio devices total).

Discord has the 2 seperate audio channels set up on windows anyway. Why is there no volume and device selection for notifications?

Note: One of the recent Windows or Discord updates broke the Windows sound options so Discord will always fall back to the default audio device (which in my case happens to be random).
