I've installed Pardus on a new laptop with the AMD A6 processor and while it's been rather nice, though naturally taking some getting used to, I've run into a problem that I cannot find a working solution to, myself.  I have it set up to dual boot (why not triple, I don't know, Pardus seemed to miss the PCLinuxOS install... but that's another/minor issue) with Windows 7 so I can and have confirmed that the hardware is working correctly.

If I try to use the external audio (headphone) jack, I get get no signal from that socket and audio keeps playing through the internal speakers.  I have tried settings in KMixer and alsamixer and it's as if the external jack simply does not exist.  If I saw it, I would have enabled it.

As such things are oft asked for, here is the lshw listing for that laptop:

And the results of 'lsmod | grep snd' :
http://www.conmicro.com/~vakko/pardus/lsmodgrepsnd.txt

Any suggestions or is there a page I've missed and should be reading?  Thank you.

I'd be looking at the pulse audio aspect.......

to miss the PCLinuxOS install...
Does PCLinuxOS use the Grub2 bootloader Huh?
If so  Wiki: Adding a GRUB 2 item in the boot-menu of Pardus

If I try to use the external audio (headphone) jack, I get get no signal from that socket and audio keeps playing through the internal speakers.
Maybe this is caused by the physical dimensions of the used plug of the headphone.
Does the plug of the headphone  switch the build-in switch of the female connector

I'm not actually sure, but I will look at that, thanks.

As I posted, I've tried it in Win7 to confirm that the hardware does work.  The hardware works.  This is a software issue of some kind.

Vakkotaur,

I had the same issue you are having, in addition my line in would not pass to the output. This was on a desktop and it WAS a Pulse Audio problem.. In one word, pulse audio Sucks. Some distros, such as Puppy and Mepis do not use it, only Alsa. My solution was to turn off my built in sound hardware and use a reliable Soundblaster Live card. I realize this does little in the way of helping you as you have a laptop, but to say it's a Pulse problem.

Sorry ,didn't mean to get all mystical on you.

Pulse Audio is the latest standard in sound production and control , some distros do not use it yet, but Pardus does. Your problem surprises me , because this s the first distro that DIDN'T give me any hassle using it.
Suggestions ? You need to look for two programs- paprefs ( PulseAudio Preferences ) and pavucontrol (PulseAudio Yolume Control ) these are graphical so they should show up in your menu, if not ,then try checking your control panel ( I don't use KDE so I can't give you a better answer than this ).

 I think this should have been auto-detected during installation , ( at least for me ) if you had had your head phones plugged in during the installation process.

I had thought I'd tried the various PulseAudio controls, but it is possible I missed one.  Taking a break from this, I installed the 32-bit compatibility libraries (once I was told the simple method how) and as far as I can tell that's the only real change.  Again, I could be wrong.  But coming back to the audio issue, I tried the Mixer settings again and got to the audio control panel and plugged external speakers in while the [TEST] sound was playing. It came through the speakers.  To be sure, I then started mplayer to confirm things.  I am now getting audio through the external jack.   Though it does worry a me a bit.  When things seem to suddenly just start working I always wonder if they'll suddenly stop as well.

Exactly as I'd feared, the working external sound stopped working after a simple re-start.  And I have no idea what incantation made it work in the first place.

Also: KMixer refuses to start. The icon bounces for several seconds then *poof* -nothing-.  I recall on initial intsall that all the file permissions were messed up - I couldn't even start KDE properly.  This makes me suspicious of Pardus itself.  That should simply Not Happen and I wonder what else is amiss.  Maybe it's just current frustration, but that does seem a very strange thing.

First the system says kmix is already there and will not be reinstalled, which makes me wonder about the reinstall option's utility.  However, removing kmix and installing it results in.. the same thing as earlier.  User sees it do nothing, root gets the D-Bus error message.

But still:

Is the Kmix icon already in the system tray Huh?
Because, when the icon is already in the system tray (this means Kmix is already activated), you get the behavior as you describe with "The icon bounces for several seconds then..." .
And "sudo kmix" is useless.

And to refresh all dependencies of Kmix a
Code:
sudo pisi it phonon kdelibs alsa-lib pulseaudio-libs --reinstall -y
might also help to solve this.
