In the upgrade from Linux 2.6.14.7 to Linux 2.6.15 the mixer item

This kernel added a "headphones only" workaround for the Inspiron 8600
that removes the headphone controls and controls the HP volume with the
master controls.
Thanks, how is the workaround enabled?
The biggest problem with this regression is that it makes it
impossible to turn off the internal speakers of the Dell Inspiron 8600
and only have sound when something is connected to the headphone port.
What is the output of "amixer contents"?
