I aquired an old Dell Latitude CPI D266XT laptop a little while back. Of course the first thing I did with it was install linux. I have everything up and running, but one problem:

no sound

I'm no sure what to do. I know this has been discussed a lot but I don't understand / it didn't apply to debian.

I am using xubuntu, which is pretty much ubuntu with xfce, which is pretty much debian.

So can someone help me get this working with debian instructions?

Also, I want to be able to use the XFCE sound plugin (if that matters)

Thanks !!

you will want the alsa sound tools, there are very good howto's on the lq wiki pages
i used those docs myself, when first having sound issues with debian testing so you should do just fine.
