Headphones not working

[Richard Allen]

I dont know what I did but suddenly my sound is broken.

I'm running Fedora 14 (x86-64) on a Dell Latitude E6410.  The problem is 
as soon as I plug in my headphones I loose the sound.  If I unplug the 
headphones I get sound out of the built in speakers of the laptop.  
After I lost sound I started experimenting with the settings in sound 
preferences and I'm pretty sure I have tested all possible combinations 
without success.

Has anyone seen something like this before?

PS: Happy new year! :)

If your machine is dual boot, find out if they work in the Other OS.  If 
it's not, try a Live CD.  It's possible that the headphone jack itself 
is bad.

I just tried this and while it did change the things available in the 
audio preferences menu it still does not fix my problem.   As soon as 
the headphones go in, all audio stops.

And its also strange that two days ago all was working fine with no 
modprobe.conf changes.

I don't have the headphone problem, but I do have this one:
https://bugzilla.redhat.com/show_bug.cgi?id=660370.

I did have a problem with sound (Skype, IIRC) and the solution was to
create /etc/modprobe.d/snd_hda_intel.conf containing:

        options snd_hda_intel model=dell-s14

Then reboot.

Not a stupid question.  But that was one of the first things I tested.   
Headphones are fine :)

Stupid question: are you sure the headphones actually work, e.g. when
plugged into an MP3 player or HiFi? I've often wasted time futzing
around with sound settings when the only problem was that my external
speakers had turned off because of a power outage.
