I've got a 2011 MacBook Air that I use for travelling.
Since I updated to Yosemite, I've been having a weird issue where it will occasionally lose all audio.
The weird part is that if I go into Settings > Audio, and go to the Output tab, I see that the sound has changed from "Internal Speakers" to "Soundflower (2ch)." This is odd, because "Soundflower" is meant to be used to capture audio. It's an input pathway.
Any idea how to disable "Soundflower" for output?
