I have an iPhone 5 and a Bowers & Wilkins A5 stereo connected to an Airport Extreme. All devices are in the same room.
I get terrible stuttering from the device: it's rare if it plays audio for more than 15 minutes without it starting and stopping. I've changed wireless channel and still have the same issue. I've even ran a ping over my router and also the stereo whilst listening to music – watched it stutter - to ensure the connection isn't dropping.
The stereo: round-trip min/avg/max/stddev = 19.896/159.759/897.963/161.648 ms Router: round-trip min/avg/max/stddev = 0.943/8.595/175.149/15.092 ms
Has anyone had any issues with Airplay?
