That's because LMMS currently can only work with 2 audio channels. Closing this as it's not a bug but an enhancement request which is a duplicate of this one #4064

Maybe we could disable that Spinbox, but since it doesn't allow the user changing the number of outputs to an invalid one this is not a priority but a minor UX issue.
