I am a brand new Mac Pro user who just switched from a PC. Have a question regarding the way the Mac Pro handles SOUND When I hooked up my Mac Pro I opted to use the OPTICAL output rather than using the smaller single jack audio output beneath it. Problem is, some programs choose on their own to output through the OPTICAL (digital out) output and others choose to use the built-in speaker. I have been able to go into PREFERENCES of individual programs (EyeTV for instance) and select DIGITAL OUT as my preference. However, there are other programs that give you no preference whatsoever on how the audio is outputted (such as iChat login sounds). Other than going into the System Control Panel -> Sounds and setting DIGITAL OUTPUT as the default, are there any other suggestions to steer all program audio through the optical out?.... ....or was I better off opting to use the smaller output jack beneath it? I even wish the almost Gong-like audio that plays through the internal speaker when powering on the Mac Pro was pushed through the digital output as well, but I know that's impossible.
