Hello, My windows 7 Ultimate x64 Laptop has one morning (2days ago) Started to act very funny, In only terms of sound though... I woke up and turned it on, Plugged in my headphones and headed to play some music, But to my surprise it was absolute garbage. There was no bass, No main vocals, And it seemed faded... But the main (Orchestra/ Beat) if you will was completely fine... So i messed around with setting after setting and i managed to fix the bass problem by changing the Decibels at which its played, (Must have been reset)... But i still hear no main vocals, All that remains to be fixed is the vocals and some metallic sounding (scratching) when i play songs with alot of bass, Any help is greatly appreciated, Also i can give any info you need... PS if i don't listen through the headphones (Which i know work, They play fine in my iPod & i got the same results with a different pair) The audio is perfect through the speakers... Please help me
