Hi, just wondering if someone could confirm a few things for me. I'm looking for a solution on how to wirelessly play ALL audio from my MBP using external speakers. I've looked at pairing AirPort Express and Airfoil but this isn't suitable due to the audio delay on video. Hence why I'm now looking at ATV. The majority of the time, the ATV won't actually be connected to a TV, only the optical cable to external speakers. Can I use this setup to ALWAYS have audio playing through the ATV unless I change the output settings? I've read reports that by mirroring the screen (even though there will be no HDMI cable connected) it will play the audio through the attached external speakers. Is this correct? Thanks.
