Gave my laptop back to the shop a week before raya and just got it back this week. 2 weeks total. Aaand the speaker is still crackling.. but it doesn't vibrate like before (jittering, vibrating sound like that).

Honestly have no idea what they did with it. I asked the seller if they changed my motherboard cause my OS was reinstalled (they did a backup of my stuff) and there was a different BIOS logo (ASUS and Intel instead of just ASUS) but he said no, only reinstalled my OS and my speaker (maybe?). I don't even know anymore. Can't send it back again for now cause I need it for work and stuff.

I also went to the ROG forum and asked if anyone with the GL552 was having the same issue and a guy said no, nothing like it. Think it might be a hardware issue on my end. My only choice right now is to either send it back again and hope for the best or bring out some cash and ask them to replace my MOBO/speaker/something
