Towards the end of 2011 I was nearing graduation for my Master’s degree in Digital Forensics from the University of Central Florida and I was looking to further bolster my resume by adding more “keywords” to it. Rather than having just Windows and Linux, I wanted to add Mac to the list, so I bought a Macbook Pro. When is the best time to buy a Mac? Purchasing on Black Friday got me a nice discount, which was then even improved upon by Amazon. Without the student discount, their pricing was still lower than Apple’s with the student discount (Apple charges for shipping).
So the Mac arrives and it works. A few weeks in and I have no sound. What is going on here? Aren’t these things supposed to be the best computers out there and Windows sucks, yadda yadda yadda? Apparently not, because I have no audio!
Not knowing much about the workings of an Apple laptop, I do what I would in Windows, I open up the Task Manager, or Activity Monitor on a Mac. To do this, go to Launchpad > Utilities > Activity Monitor. (There is no shortcut to Activity Monitor, but you can create one or use Spotlight by pressing Command + Space, then start typing Activity Monitor. By default, Activity Monitor opens with My Processes displayed; I don’t want My Processes, I want All Processes, because it’s going to be running at the system level.
Activity Monitor has a great feature in the upper right, next to the dropdown to select All Processes, called a search filter. If you search for sound, nothing appears, BUT if you search for audio, you get one process: coreaudiod. Notice that the user is _coreaudiod, so this would not present itself if we were searching in My Processes.
