I need to add

hw.audioInput=no hw.audioOutput=no

to every AVD I create. Otherwise, the Android Emulator uses 100% CPU all the time, even when it's been idle for minutes.

I'm far from the only one having the problem, see https://stackoverflow.com/questions/37063267/high-cpu-usage-...

I'm on a Macbook Air 2014, Intel i5, 8GB of RAM, 500GB SSD. Hardware acceleration, etc. all enabled.
