1 week old MacBook static noise from both speaker and audio jack
I am at a loss and desperate. Already did a few SMC reset and PRAM reset as well. I just bought my new MacBook 12" a week back and this evening when I plugged in my headphone it was only static noise. later I was making a call and could hear the same static from the built in speakers. And to think I was falling in love with these speakers everyday. I played both audio and video files but the static noise will not go away. I am devastated. I searched everywhere for a solution but this problem is not mentioned anywhere for the new MacBook 12". Any help will be greatly appreciated.
MacBook (Retina, 12-inch, Early 2015), OS X Yosemite (10.10.4)
