pds41: Usually, it's a system issue rather than a specific game issue. I know it's a very basic question, but are other games working through your headphones? How are you flipping between speakers and headphones - hard switch or soft switch?
Jmaaan998: Singularity is the only game this is happening with.When i use my headphones i cut them off and when i use them i cut them on.They are wireless is also.
Hmm. Not sure I can help then. My wireless headphones are radio ones, so connect through the headphone jack on the sound card. My soundcard uses a software switch in the drivers to shift output from the standard 5.1 jacks to the headphones one.
Have you checked volume mixer when the game is running with headphones engaged (the one in windows settings) - for some reason, the specific game might be muted when running with headphones.
