I have a home network with three Macs: MacBook Pro, Mac mini, and iMac. I have an Airport Express connected to my hifi (2007 model, 802.11g). It used to work flawlessly, but now whenever I try listening to music from my MacBook, it plays for a few seconds, then goes silent for a second or two, then continues playing. It just keeps going like that. It never used to. It doesn't do this when playing music from the iMac and Mac mini, only the Macbook Pro. I've tried resetting the Airport, and changing settings in iTunes on the MacBook, but nothing works. Does anyone have any idea what the problem could be?
