Hi,
the builtin sound card in my laptop does not behave as it should, when running it with the ALSA system. While there are separate mixer controls for headphones and speakers, the Master control levels both, speakers and headphones simultaneously, while the headphone control does not act at all. Also in my opinion the speakers should mute automatically as soon as I plug in the headphones, this does not happen too.
I am running Ubuntu 8.04.1:
$ uname -a Linux monostatos 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 i686 GNU/Linux
$ lspci -nn |grep Audio 00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02)
If you need any more information about that machine, or if there is anything I can do to help fix that problem, do not hesitate to ask.
First of all, show the h/w vendor and product names of your laptop. Then run /usr/sbin/alsa-info.sh with --no-upload option, and attach the generated file to here.

PS.: I also published a lengthy rant, and some ideas about that problem at http://propirate.net/oracle/archives/2008/11/05/alsa-headaches-erm-headphone...
Well, there are more different things behind the problem than you wrote there :)
- broken BIOS - broken driver implementation - missing preset model implementation - insufficient mixer setup - sticking with older version - financial crisis
thanks,
