Usually it's just a matter of switching profiles/ports by hand. You can
do that in the sound capplet in gnome.
If you want to do this on the command line you could do that on the ALSA
level (i.e. find the right contro to switch with "alsamixer -c0", and
then put together an "amixer -c0 ..." line doing the same.) Or you can
do this on the PA level, simply use pacmd to execute the port/profile
control command you want to execute. Use "pacmd help" for help.
