Audio problem - No sound - Mac Mini
If this is covered elsewhere, please excuse the duplication and point me to a link or thread. Thanks.
This problem began out of the blue a week ago. Happens randomly -- sometimes everything is OK, sometimes the Mac Mini exibits the symptoms below. I haven't installed or changed anything. Anyone have any ideas?
Symptoms:
1. No startup sound.
2. System Profiler lists "No Built-in Audio" (when working OK, the list says "Intel High Definition Audio, Device ID 0x83847680, Audio ID 8, Speaker Connection: Internal, etc.).
3, External Logitech speakers plugged in, no sound. I unplugged them (when mini is working OK they're fine).
4. No volume control icon in Apple menu bar (when working OK, it's there and turned up).
Tried (no results):
Shutting down completely, waiting a few minutes and restarting.
Resetting PRAM (holding down Command-Option-P-R while starting up).
Used Disc Utility to repair permissions.
Used OnyX (excellent 3rd party utility which often finds things Disc Utility doesn't). Ran a full diagnostic with it... it found and repaired some permissions but noted no other hardware or software problems.
My best guess:
Motherboard dying?
Stats:
Mac Mini Intel Core 2 Duo, 2 GHz processor, 1 GB memory
OS X 10.5.8 (can't upgrade because 3rd party legacy software I use won't run on latest OS X)
Purchased Mac Mini in April, 2009
It's been a great little box but this is rather frustrating. Any help is appreciated.
