Howdy Folks, Week 4 of MBP SR ownership delivers issue #4! After the Yellow/Mauve blotchy screen, random kernel panics, and font issues I now have no audio. Now before you say that I've probably *ucked ($* = M) up my sound preferences, this is my 6th or 7th OS X Mac and I'm a music teacher so I'm well aware of the settings in there. No, this is new to me, Sound Preferences indicate that no input or output devices can be found, and in the Sound Effects dialogue panel, the alert sounds are all greyed out. As expected all volume sliders are also greyed out. My gut feeling is dead sound card? I have the 'show volume in menu bar' option checked, the 'mute' option is checked but greyed out. Incidentally, on restart, which has been tried to death, the menu-bar volume icon disappears. I've run the extended Apple Hardware Test to no avail. I have verified and corrected permissions and am at the stage of contemplating .....suici... arhhm......a re-install. This is not desirable as it's taken me over 3 weeks to get my (100+) applications installed and running correctly. Note machine was running OK till I installed Illustrator CS 3, which I have since uninstalled using the Adobe uninstaller.
