I have recently installed Ubuntu 14.10 on my Asus X75VD. Everything works just fine except for these little sound chops I get whenever I watch a Youtube video in Firefox or in Chrome. Video and sound are perfectly in sync. It's just that every two minutes or so one or two syllables of a word disappear and you get this skipping sound (hard to describe. it sounds as if someone accidentally pushes the search button on the stereo).
I have both alsa and pulseaudio installed. However, I can't tell through which of these the sound from youtube runs through.
The soundcard is a HDA-Intel - HDA Intel PCH.
Any ideas or experience?
