Hi,
You have rather new laptop, right? So most probable is that you have
soundcard based on HDA chipset, you could check this with this command
(type it in your favourite terminal emulator, like xterm or gnome-terminal):
$ lsmod | grep hda
If you see something like "snd_hda_codec" it means that you have it :)
Now from Kernel documentation:
"Another related problem is the automatic mute of speaker output by
headphone plugging. This feature is implemented in most cases, but
not on every preset model or codec-support code.
In anyway, try a different model option if you have such a problem.
Some other models may match better and give you more matching
functionality. If none of the available models works, send a bug
report. See the bug report section for details."
It basically means that driver for your card is buggy, or is wrongly
advertised by BIOS to kernel and bad driver is assign to handle the
card. In that situation you could try to manually assign it. At [1]
you've got comprehensible thread what to do with it. I hope that help :)

Since the change from Win 7 to Arch there is just one function I really
miss up to now. Perhaps someone of you can help me out.
Is it possible that Arch deactivates the internal speakers of my laptop
when I plug in my USB-headset and turn input / output to this ?
In Windows I could define the USB headset as default for in-/output so
Win made a fallback to internal speakers only when I plugged out the
headset again.
It would be really great if Arch was that comfortable too. I know in
GNOME there are just two clicks to do for switching to another audio
hardware but ... :D
Warm regards,
Nelson.
