I've just bought a new Macbook Air 13'' 2013, and everything seems ok so far. But I've decided to upgrade Snow Leopard to Mavericks, and weird thing has happened: when sound volume is high, I can definitely hear sound distortions coming from Air's speakers. I'm absolutely sure that Air didn't have these distortions on Snow Leopard.
Is this a known bug, a hardware issue, or an expected behavior?
Thank you in advance.
