I am using an IBM ThinkCentre (M/T 8215-29U), which has an Intel N10/ICH 7 Family HDA Controller (rev 01). The speakers plugged in to the back work fine, but the microphone jack on this system is in the front, and it isn't working with Fedora 15 (it did work with Windows XP).
I have tried running "alsactl -c 0" and made sure all the volume bars are up, as well as checking things in the Gnome sound applet, but the applet (nor sound recorder or Skype) process any input from the microphone.
I need this working so I can continue to use Skype for work. Does any one have any thing I can try to get this working?
