I use a lenovo G460 laptop with windows 7 64-bit. for the past few days or so i've been noticing that the laptop would mute itself especially when im watching a movie or using some media player. I would get a windows sound after a while, now after this sound a few minutes later it would mute itself. Then i have to use the mute/unmute option in the keypad to get back the volume. what could be causing this trouble??? any help??

ship your laptop back to lenovo. mute/unmute problem was a "launch board" failure.

You can test your sound hardware to discard any OS related problem.
But, if the problem persists, so it's located on hardware.
