I just started my new job as a web designer and my boss knows I'm a Mac guy, also he wants to test out his new site on an Apple platform. He bought a Mac Mini for the office. I tried using iTunes to play my music, but for some reason, the volume's disabled, and I checked the system preferences under "sound" and the "built-in audio controller" for the sound output device is nowhere to be found. All the volume controls are all greyed out. I also noticed that iTunes refuses to play anything when there's no audio controller. Can anyone shed some light on this issue? I tried searching for answers on this board, but I've come up with irrelevant results. It's weird, I hear the chime when I turn on the computer. So I figured it at least has a mini speaker built in, therefore it must have a built-in audio controller. I coulda swore on any Mac Mini you can just plug in speakers and you're good to go. He will be using the machine to edit videos using iMovie too and it would suck if he had no sound. I don't know if it matters much, but we're using a non-Apple keyboard (some random Compaq keyboard we found in the office) on that machine. I'm gonna talk to him about buying a Mac keyboard since we'd need that silly CD drive eject button, the sound controls, and the Apple keyboard's more familar to me. Using the "windows" key as my command key is weird. ^_^; So in a nutshell. No built-in audio controller found on the Mac Mini I'm using. Just simply plugging in a pair of speakers doesn't help. So what do I do to get sound? It would be silly if one were to pay $600 for a Mac Mini, but someone would have to buy a $100 external audio card/device via USB or Firewire just to get sound. Any help? Thanks for your time.
