Audio problem fixed on my MacBookPro
Audio stopped working on my work-provided MacBookPro recently, and I was able to fix it by reading this thread and applying the suggestion (I used a coffee stirring stick/straw). http://discussions.apple.com/thread.jspa?messageID=3255575 Basically using my regular stereo headset confused the headphones/digital audio port into thinking I was connected for digital audio only.
