I have been trying to start and stop Amarok from the command line. I can do this from a terminal with /usr/bin/amarok -p and /usr/bin/amarok -s. When I place these commands into gnome schedule, nothing starts or stops. I am using Ubuntu Gutsy (7.10) with Amarok 1.4.7.

you need to use dcop to control amarok from the command line.

dcop amarok player play

dcop amarok player pause

There are tons of commands to use, you can just use a dcop browser to see them all

dcop, one of the main reasons why GNOME sucks and KDE is teh r0x0r5
