Roblox Studio audio is just straight up broken, I tried so many different methods to fix it but its still bugged.
I tried on different computers and its still bugged and no its not from me locally since other users I know have the same bug.
To bring this back up, this issue is related to “Only Play Audio from Window Focus” and when having this on, and playing and then exit focus and refocus, audio does not re-enable when re-focused back onto studio. disabling this setting fixes audio, preventing you to unmute but keep audio on forever until u mute it
