Hi. When I am using headphones on my laptop (Realtek audio) with Mint 17x64, I hear constant buzzing noise at very high pitch. It doesn't matter if I am playing something, or just idling. It is not very loud, but it's extremely annoying. I cannot enjoy music or movies with it, but mostly I can't bear to wear headphones on, when idling. It stops for a few seconds when a new sound starts to play - e.g. when i open an mp3, but then it's there again, like nothing happened.
I am using dualboot with windows, but in windows everything is ok.Then headphones are OK, too. Tried them on a portable player.
Thanks for any help.
