I'm running Hardy on my Dell Inspiron 1420n. Everything works great, except.... I have been unable to get output from the headphone jacks on the front. (Sound is fine from the speakers.) Nothing I've tried gets sound to come out, and plugging a headphone into the jack(s) does not mute the speakers.
$ aplay -l reports:

I think I've got the right settings in alsa-mixer. Master, Headphone, PCM, Front, and Surround are all enabled, not muted, and set to reasonably high volume levels. I've seen a variety of suggestions for settings. One I've tried is to set "Mic as Output".
I've tried a couple of settings in /etc/modprobe.d/alsa-base, setting options snd-hda-intel model= to "dell", "dell-3stack", etc. No luck.
Any help would be appreciated. Thanks.
