# Change bluetooth audio parameters on OSX to solve dropping/choppy audio problems on Yosemite 
# (and earlier, reportedly) w/ BT headphones. This is not a perfect solution, but reduces

# iTunes local audio only; please leave a comment if you discover it causes any problems with AirPlay
# or other software.
