system sounds

[H H <dr.hugo.z.hackenbush@gmail.com>]

Hi, wonder if anyone can give me a clue to getting the system sounds 
working on my lenny 64bit? All other sounds worked fine so i installed 
esound which got system sounds working but my skype and youtube stopped 
working. I have uninstalled esound to get skype and youtube back 
stopping the system sounds again so is there a way to have system sounds 
 with skype sound and youtube working?
