Hello all,
After pieces of feedback we've received, we discovered an issue with the audio output selector in the game UI. As we're unable to test this on mass we have released this update on a Beta branch. If people could test this branch and submit any feedback via the in-game bug reporter that would be amazing.
In order to access the beta, right click on Atelier's Key, and click Properties
Next navigate to Game Versions and Betas and select the Beta branch.
And that's all!
Thank you everyone who have played and provided feedback so far!
