Now that Core Audio works, reduce the number of build permutations a bit

Browse Source 
by not linking in other Unix audio modules.
 
Use kAudioUnitSubType_DefaultOutput instead of kAudioUnitSubType_HALOutput
so that a runtime switch to another audio device is automatically handled.
 
Use ERROR_LOG for audio errors.
