I'm not really sure what it's product number is..besides it being the pavilion dv5.
It's Windows 7 and yup, when it uses the built in speakers (which I actually got fixed 2 months ago because I spilled water on the original speakers) the sound slurs.
It slurs in a stuttering way...almost like a CD skipping.
Also it slurs while playing music from all sources (computer, pandora, youtube)
Thanks!
