Thanks, Clemens;

How were you able to determine that from the "amixer scontents" output.

Although I can't disable *automatic* speaker mute on headphone 
insertion, can I explicitly unmute them again (e.g. with amixer sset or 

If not....
"cat /proc/asound/card*/codec*" says it is the Realtek ALC888.
Does this mean I have to somehow patch the kernel sound module file
to fix this somehow?
