Sound missing after spark sound - broken speakers?

Hi there! I've got a MacBook Air 2020 that works fine, but sometimes the speakers make a weird noise, almost like a spark or if there's water in there. It's kinda freaking me out. When the speakers make this noise once, the Mac stops producing any sounds. I can't hear a song or the sound to a video. It sometimes happens, not all the time.

The weird thing is, when I restart my Mac, the sound from ex. videos and music return.

If this only happens sometimes, should I send it in for repairment? Or should I not do it? Is it something that happens to any of you?

Thanks in advance
