How to make media players to get mute when Skype takes a call?

Skype mutes Amarok in OpenSuSE 11.4 on incoming or outgoing call, immediately after a conversation has been switched off Amarok continues to play. How that could be done for other players as vlc and clementine. I tried to use the Public API section in the options of Skype, but it doesn’t allow any change from default settings.
