Airplay sound delay when watching online content with wireless speaker.

I recently purchased a wireless speaker with airplay capabilites. One of the main uses I wanted it for was to play the sound while I was watching netflix on my tv through my MBP (late 2012 edition with latest mountain lion OSx) hooked up with a Mini DisplayPort . When playing a movie through iTunes there is no sound delay, but when I go online and watch something on netflix there is a 3-5 sec. delay.

Is there any way to connect this delay without having to buy anything or download any 3rd party apps?
