Hey Guys- Today I went to use my MacBook Pro and my headphones, only to find that it's audio out port isn't working! It doesn't appear in System Preferences and I think it appears in the System Profiler, but I'm not sure: Code: Intel High Definition Audio: Device ID: 0x106B00A0 Audio ID: 44 Available Devices: Speaker: Connection: Internal Headphone: Connection: Combo Microphone: Connection: Internal Line In: Connection: Combo S/P-DIF Out: Connection: Combo S/P-DIF In: Connection: Combo I'm running on Mac OS X Leopard 10.5.1, 2.4GHz MacBook Pro with 3GB of RAM... 15". Help? Also, here is what I see in system preferences. In Output & Input. P.S. I've tried restarting, but that's it. EDIT: I tried resetting the PRAM, a few more restarts, and running a disk repair permissions. Nothing. Anybody have any idea?
