Hello, currently I'm using my Turtle Beach Ear Force Z2's, and normal speakers. Earlier I could hear everything just fine, then I came back to my computer and plugged my head set in and couldn't hear anything, then I tried with my speakers, still nothing. I restarted my computer and now I can only hear the test sounds from Realtek HD audio manager. Also I am able to hear sound from Skype. Right now I'm testing random programs for sound.
