You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one. Post in the El Capitan community.
Did you try this?
). How do I un-install Soundflower?
1. Click "Go" on the Tray menu (upper left).
2. Click the "Go to Folders" item.
3. Type "/System/Library/Extensions"
4. Find the file "Soundflower.kext"
5. Remove that file, and then re-start the Mac system.
6. Open System Preferences -> Sound -> Output.
You should not see SoundFlower any more in the Output tab.
