hi, I was using some headphones with a separate mic / headphones jack and up until this morning, they were working fine. apparently, the microphone part is still fine, because multiple people could still hear me over skype and my computer "says" that it's receiving audio from the mic. the problem is, I hear no sound form the headphones! my computer isn't muted because I can hear the sound without headphones and with multiple different pairs of headphones. my computer also recognizes that headphones are plugged in, so I don't think that's the problem. when I try to test them, no sound comes out. help please!
