are you playing on the browser or downloadable version? the browser often has audio glitches. I'd recommend downloading it and not touching any of the audio settings for the best experience! sorry for the frusteration!
i played the downloaded version (also finished it after writing the comment, it was amazing! i absolutely loved it ദ്ദി(｡•̀ ,<) ) and i noticed that the voice acting would work again after the music restarted? it might just be something on my end though!
