the instruction remains the same and is still supported - just change the output API in the Player preferences to DirectSound
Nevermind! It was a problem of mine missing some wine libraries since I'm on a fresh install.
New version works out of the box with WASAPI.
If everyone is wondering, you also need to install Net Framework 4.6.1 or the new version of MusicBee won't start.
Anyway, thanks for the reply as always
