Another studio problem,

The built in array mic, does not work. It shows up in system profiler as

'Intel High Definition Audio:

Device ID: 0x1028029F
Audio ID: 12
Available Devices:
Microphone:
Connection: Internal
Speaker:
Connection: Internal
Microphone:
Connection: 1/8 inch Jack'

Although in System Preferences it does not show up. There is nothing under 'Input' in 'Sound'.

Cheers,

Dan
