I have a laptop computer, whose speakers suck, so I usually use headphones or a really nice pair of Harman Kardon speakers. Starcraft 2 will play sound through the speakers and headphones just fine.
If I try to play music while playing the game, the music ONLY comes out of the laptop speakers. It WILL NOT play from the plugged in speakers or the headphones. I seriously do not understand this problem.
Blizzard, please help me fix this, I have made a few posts in the past, to no avail. Tell me what you need to know. TELL ME, BLIZZARD. DANCE THE DANCE OF LIFE WITH ME.
