did everything just like you said. Tried 2 different headphones/speakers and reinstalled all my audio drivers twice. Default audio device for osu is set for what I usually use last month while it was still working. Reinstalled osu 5 times. Yet it still doesnt have any sounds, z and x(left click and right click also) doesnt work on circles. Doesnt appear on volume mixer. Thanks for the suggestions/tips but still in trouble here. (also THIS only happens to osu alone)
