Welcome on the band of snd_intel8x0 guys.!!!
I have your hardware and same problems. Many bugs related, it seems
connected to incorrect time scheduling of kernel and related drivers
I had these problems since end of F9, switched to F10 but no real
improvements (i.e. if I run Rhythmbox and I listen to a radio stream I
note many breaks and buffer becomes empty)
Try pulseaudio -k then pulseaudio -vv in a terminal and you will see
many interesting warnings (rewinds and so on).
Now some improvements with alsa-lib-0.19 but I am running F11, I am
waiting for 29 series kernel tha unfortunately don't boot at the
moment on my hardware
Have a look to:
 Bug 462026 -  music file play -> sound sparks.
Bug 447594 -  audio going through pulseaudio causes skipping, dies
Bug 446192 - horrible skipping audio
 Bug 441087 -  Sound/music playing faster than it should on intel chipset

IMHO this bug has been underestimated for a long time
