This question has been here for a few times already, still no reasonable answer has been given yet.
I have bought a brand new notebook and installed audio drivers and codecs, everything works just fine but headphones. When I plug them in I can hear murmuring, popping sound - even when the music is not playing. I'd decribe the sound as the sound in headphones when you have volume on maximum and not playing music but ten times worse. I tried to reinstall the drivers, older drivers, different drivers. Nothing works. I'd aapreciate any help. Notebook is Lenovo IdeaPad Z510. Drivers directly from Lenovo don't help either.
BTW: I had the same problem on the old notebook, which was solved by installing the older driver.
