I have an issues about sound crackling.
I bought Y510p around OCT 21st and everything was fine except the sound, so I send my laptop for Depot repair service.
However, the problem was not solved, so I send it again.
But again, much to my disappointment, It wasn't fixed at all.
Here's what they've done for my laptop.
1st attempt: replaced motherboard, speakers and reload OS
2nd attempt: replaced motherboard, speakers, audio jack, OKR and reload OS
I also tried settings and drivers stuffs in the forum, but It wasn't helpful.
One solution that changing power mode helped a bit, but it was a temporary expedient.
Lastly, I bought an external USB sound card and tried it. Unfortunately, this one wasn't helpful either.
