Help! Where Do I Plug My Headphones?, Problem with basic mixing Options

[danhoritz]

I own a powerbook g4 and have recently downloaded some dj mixing software like dj1800, obelisk and tactile. However I have not been able to make a single mix as I'm not sure how to plug my headphones in alongside my speakers which use the headphone/line out socket. The other socket seems to be intended for speakers (it has a picture of a circle with two triangles coming out of it!?) but when i plug them into it the sound continues to come out of the built in ones.

Do I need a new driver so the other socket will recognise my speakers? Or perhaps a splitter so i can plug headphones and speakers into the same socket?


Any help would be much appreciated!

Cheers
