I recently purchased a logitech usb headset with mic to use for gaming (eve). Neither audio nor mic work in game. I tried using the headset to listen to music using audacious; no sound. I played around with Kmix (turning inputs/outputs on/off and adjusting the sliders) and get nothing. An odd thing I noticed: I can hear myself in the headphones (through the mic) but not on my speakers, nor can anyone hear me ingame. I can hear other players just fine on my speakers, but not on headphones. I am running kernel version 2.6.25.18-0.2-default. The output of /sbin/lspci:
