Sound card problems: HDA Intel (STAC92xx Analog)
 

I just wanted to start by saying that I am completely new to linux so please include all steps necessary. Thanks.
I have been running Pardus on my Dell Studio laptop and while sound works out of the internal speakers, when i plug in headphones, the music stops from the speakers but doesn't play in the headphones. I had the same problem in openSUSE on the same computer.
Any help?
Thanks.

Have you tried to run in the terminal and see if your headphone output is muted?

The headphone jack is at full volume, along with all of the other volume bars.

Try the 'model=3stack' option to the snd-hda-intel kernel module.
The above line will need to added to an appropriate file in /etc/modprobe.d/
I do not know Pardus, so you may need to seek advice there.

Edit: As root in a terminal, execute 'echo "options snd-hda-intel model=3stack" > /etc/modprobe.d/snd-hda-intel.conf' and reboot.

When I type that in, I get
bash: echo"options snd-hda-intel model=3stack">/etc/modprobe.d/snd-hda-intel.conf: No such file or directory

By the way I decided to switch distros from Pardus to openSUSE, I hope this is helpful, it hasn't worked in any distro, though.

That didn't work, unfortunately. In the same folder I have a file snd-hda-intel.conf. In it is the coding: options snd-hda-intel model=3stack. Could this have something to do with it? In KMIX there is only one channel for the internal and the same on alsamixer. I can get other channels by selecting the soundcard (pressing F6) and there is the option for headphones there, but it doesn't do anything.
Thanks for all of the help.

Try changing from 'model=3stack' to 'model=dell-m6'.
If that does not work, please post the exact model of your machine.

That worked,
Thank you so much!!!!
