Hi All,
Just got an HP Pavilion G4 1315 au. Have very basic usage since i already have a desktop.
It does not ship with a driver Cd, so i downloaded all drivers from the website and installed. All running fine except one.
When i play music or video files, they sound perfect all right on the internal speakers, but when Headphones are plugged in, the background musics seem fine, but the vocals are all screwed up.
IDT Audio Drivers which i installed. SRS Premium Sound Manager which does not have a stand alone option for headphones.
Can somebody tell me what is wrong ?
