Same as the previous one! this also has working sound not a single muffeled sound or missing sound in any of my games. Something with these new playlists make it happen and its worth looking in to in order to fix the core modes sound.
The devs have said they are working towards a solution to the sound issues, and hope to have a fix in Y5S1! I can't say for sure if these changes have been implemented for the new playlist, but I'm glad to hear the sound has been working better for you!
