SVE1112M1E headphone problem
When your PC plays music or video, what type of sound output do you get; normal or robotic?
If its normal, you may have to test/try out another headphones and connect/plug in to your PC and listen once again to the output sound.
Is it same as your previous headphones is; sounding robotic or is it normal?
Normal sound output in the new headphones (not your previous headphone), you know the answer.
Robotic sound output with the second headphones? You mahave to reload the drivers if this'd help.
However, simply hope problem is not with your PC's sound jack
