Setting an audio output device

[Ploctor]

Alright, so I might be overlooking something, or I'm just messing up something super simple.

I want to be able to play the sound played in LMMS, to a specific audio device, so that I can use that in combination with a virtual audio cable, to play my piano directly into a voice chat.
I know that I technically could use stereomix, but due to that picking up everything on the pc, it doesn't accomplish what I want.

But when I go through the audio settings I don't see a place where I can say "Use this device as the audio output"

Sorry if it sounds confusing, tried to phrase it properly, have a great day, and hope to hear from you <3

There are no feature for that. LMMS outputs to your pc soundcard, and any specific mixing into channels or similar as you are looking for, must be done on the soundcard.
Open the UI for that and see if you can find an advanced mixing feature.
I btw do not know of any DAW with that feature.

Besides that, since you are new in Forum
