Sound problem in Backtrack 5 R3

[Cerib]

Hello fellow backtracker's,

This will be my first thread (and first post), but not my last!

I have been a frequent user of Backtrack since B3 so I know some of the tricks, but now to my problem.

-----------------------------------------------------------------------------------------------------------------------

The issue that I'm having is that I have no sound, at all! I'm running my backtrack iso on a MacBook pro 2009(?) (only installation) and I cant get the audio to work.

I have tried with the pulse audio fix with the autostart command but still no success.

I have tried searching here and on the web for issue's like mine, but I only come across the "pulse audio"-fix.

So if you have any tips for me or any questions just let me know! Here is mine lspci/lspci -nv


lspci:

I just wanted to make a quick update,

apparently the sound works, but only if you have earphone plugged in.

Any thoughts?
