Hi,

I don't know how peculiar my problem is, but I'm unable to to hear audio when I play video files on my Dell Laptop (Inspiron N5110). It is about an year and a half old.
My speakers are working perfectly fine when I play any other sound file (like .mp3, Youtube videos and sounds online). It seems that only audio of video files is affected. I cannot watch downloaded videos on my laptop! Please help! :??:
