Sound will not come out of headphone jack
I will try to be as specific and thorough as possible here. I'm running Fedora 14. The speakers work fine on my laptop. However, I have logitech z 2300 external speakers, which plug into the headphone jack. They will not work. It is not the speakers, no sound will come out of any headphones either, so it is clearly the headphone jack. lspci gives me this as my sound device, "Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller". I checked the volumes with alsamixer, and it shows that the headphone jack is at zero, however it appears that I can not toggle the volume at all. The master volume and other settings will all toggle, just not the headphones.
I am baffled, any ideas?
