i am having problem in playing hd videos on my laptop. they are not playing properly or smoothly whenever i maximize my volume near about 90. when i use earphone or head phone videos are playing properly.. i am using sony vaio e series sve15135cnw..
Use a lower volume...
otherwise go download the proper drivers for both your audio on your laptop, and your video (will be from either intel site or amd site depending on the specs on the laptop)
