Hi,
I was having the exact same problem on my Dell Studio 1558 (sound through the speakers, but none when using headphones). After some more google-ing around, I found this doco:

I found my card model using this:
Code:
cat /proc/asound/card0/codec#* | grep Codec
which returned:
Code:
Codec: IDT 92HD73C1X5
This file: /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz lists the sound models with available modprobe modules to use.
Code:
zless /usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz
The full model number wasn't in there, because the model has been wildcarded. I searched for
In this section there are several PC models listed, find the one that best suites you (I used 'dell-eq').
After a reboot, I had headphone sound again.
Cheers,
Paul
