So I'm running windows 8. When i go to the sound options in control panel, i do the test button. I get the right sound. But this is on my headphones. For my speakers, everything is fine. But when i plugin my headphones they work as my speakers.. And when i do the test sound, it works. When i go on ANYTHING else, the sound is glitched or when i hear a song i dont hear the voice. plz help..
