u/Cumulonemusincus

I have this weird issue that the sound works once, only when I turn the macbook on and then it stops working for the built in speakers. But if the first sound I play is a youtube video, whilst the video plays the sound works perfectly, also for all other apps. I tried reinstallong the OS, making new profiles, nothing worked. The only thing that brings the sound back is putting it to sleep, and logging in afterwards. (MacBook Air A1932)
