First, I would like to thank you all for a nice sound experience.
ALSA has always worked fine for me on other PCs / laptops until now, with this laptop, I bought 6 months ago.

Headphone 1 plug to front speakers
Headphone 2 plug to center and LFE
Mic plug to rear speakers
speaker-test -Dplug:surround51 -c 6 -twav
With the stock 2.6.26.2:
I have only sound in front speakers spoken as "front left" and "front right".
If I unplug Headphone 1, I have sound in internal speakers spoken as "front left" and "front right",
I have sound in rear speakers spoken as "rear left" and "rear right".
I have sound in center speaker spoken as "front center".
I have sound in subwoofer (LFE) spoken as "rear center".
So, basically, everything works, except pluging in Headphone 1 to front speakers will mute all others.
I have tried:
modprobe snd-hda-intel model=dell-3stack enable=1
modprobe snd-hda-intel model=dell-5stack enable=1
modprobe snd-hda-intel model=3stack enable=1
modprobe snd-hda-intel model=5stack enable=1
and others
With same results. Some give me option in alsamixer: "Mic as O(utput)" but it makes no difference.
I have tried kernel 2.6.26 with same above results.
Then I tried alsa-driver-1.0.17. This gives me the same above results.
Then I tried alsa-driver-1.0.18rc1. This gives me different results.
Both tested and installed with:
rmmod snd_hda_intel snd_pcm snd_timer snd_hwdep snd soundcore snd_page_alloc
../configure --with-cards=hda-intel --with-card-options=all
sudo make install
modprobe snd-hda-intel (no other options given)
All 3 jacks plugged in gives me now sound in both front speakers as usual.
I now also get sound in center and LFE, but spoken as "rear right" and "rear left".
So I have to swap Headphone 2 with Mic and have sounds in both front speakers and both rear speakers.
But no sound from the Mic plug to center and LFE speakers.
No matter if I use modprobe snd-intel-hda with no "model=" or with "dell-3stack" or several other possibilities, there is no change.
In all the above I have also tried different probe_mask options with no change.
I have searched the net and tried several of the suggestions, but no change.
I have tried a quick search through the source code, but it is not obvious to me where the muting af Headphone 2 and Mic is happening when Headphone 1 is plugged in.
Since I have sound in Headphone 2 while Headphone 1 is plugged while testing alsa-driver-1.0.18rc1, it suggests it is a software issue to solve.
Also, it seems that the next version of ALSA changes things as front and rear work, but center and LFE are dead. And needs a swap in plugs.
Please give me advice how to finish setting this up correctly.
Any patches will be tested with great enthusiasm ;-)
