Hi I just bought a 2.4 MBP model a1260. When I got home i noticed the volume keys were not working, and then i noticed none of the function keys were working properly. (example, f12 shows an eject CD symbol). So, the keys are working but not doing the standard functions such as volume and brightness. I have check and unchecked (and restarted) the "use all f1, f2 as standard function keys" to no result. Some other wierd things that seem to be related are: 1. In the SOUND window in SYS PREFS all sound effects are greyed out. Under OUTPUT and INPUT it says no devices found. 2. When i go to the itunes store in itunes and i double click on a song, it wont play. Not only is there no volume, but song wont play. Its the same with my own music from my cds. 3. When i insert a DVD no volume control shows up. And the last superwierd thing (haha) is that I reloaded leopard and when the computer restarted up after install there was no OSX music that normally plays as the video flys thru the starfield. Headphones have no audio either. Sorry so long. The computer has no warranty of course. Any suggestions ??
