hello everybody ,
i have installed Leopard ( 10.5.2 ) and installed the sound driver perfectly , but i have a problem .
the problem is when i connect the headphone the sound still coming out from the on-board speaker ,
and when i connect the in-line ( mic. ) no input signal
i hope you can help me

This is the best you can get for the 9200 at the moment.
Well, maybe. tbcarey
released a version that supposedly fixes these issues, but it only works on the Dell Inspiron 6400. I have a Inspiron 9400 (e1705) and am not able to get it working. (That said, I suppose I could be doing something wrong.)
Good luck!
