Can I have audio from my PC output to Bluetooth while my video outputs to AirPlay? As it stands, my Apple TV is hooked up directly via HDMI to my television. I have 2 amazing speakers that I use bluetooth to connect to and play from when I'm NOT using AirPlay. When I switch to AirPlay, the sound comes from my TV speakers which sound terrible, instead of my higher-quality bluetooth speakers. 

Can I cast my MacBook's video stream via to the TV via AirPlay, while routing the audio through Bluetooth instead of my TV Speakers?
Just figured it out - 


Connect to AirPlay, so that both video and audio streams are going to the TV
Open System Preferences > Sound. Click "output" tab. 
Select your bluetooth speakers. 


Voila.
