Ok, system needs two recognized sound cards. I assume that in all options the external is the default. Under System - Preferences - Sound it is possible to choose a Device. I choose the internal one and mixer PCM (for keyboard volume change). A standard user would think that's it, now internal sound card is the default one but if I double click on the volume applet in systray my external is still the default one under Gnome Volume Control. So I change it under File - Change Device - to internal. Now it should be OK but if I want to change volume through left click on the systray volume applet symbol it is still the external mixer so I have to click on the volume applet symbol with the right mouse button and choose Preferences to set the sound card and mixer. Now it should be Ok but if I play a sound file it is still routed through the external since all these changes has no influence to asoundconf so I have to run "asoundconf set-default-card Intel". Now it is working after changing settings at four positions. And most of the settings have to be changed again after switching sound card.
