Nah just the green stereo output on the motherboard. My speakers don't have digital inputs so I can't try the optical out either.
It doesn't work with the green jack on the back or the headphone jack on the front (which works fine in everything else). That's all I've been able to test.
BF3 is the only program that this happens in. Rage, Crysis 2, Just Cause 2, Crysis, Skyrim, TF2, Dead Island, Borderlands 2, and any other thing I've ever done on this PC works fine...
Google search reveals others with this problem, but none of the suggested fixes have worked for me. I even tried uninstalling the audio driver and using the one built into Windows.
