Hello! I have some issues with sound on my Sony VAIO VGN-CS390 laptop. It looks like buetooth disturbs sound on my laptop. I have noticed recenly that sound becomes bad (a lit of noise, and it like slows down while video goes ok) at some moment. It becomes normal again only after I restart computer, but then problem comes back again. Today I have noticed that if I switch the bluetooth off then sounds becomes better (not sure if it becomes perfect, but definitely better). Did anybody faced such problem before? what could be the solution for this? Thank you.
