problems with sound

Good morning / evening.
I have weird problem with sound output in musescore 4.0.1. I have download all sounds from musehub base and try every possibility combinations I could think of, and stil, it was like program had some dificulties with playing writed notes. Sound is slowed down and reverbed with metalic sound.

What schould I do to make it sound like it supouse do be?

Thank you for quick reply.
