Static while playing music through AirPort Express
I have a set of Altec Lansing multimedia computer speakers connected to my AirPort Express. The plug is the standard 3.5mm headphone jack on the speakers, which are connected to the AE unit without any adapters or converter cables. While playing music wirelessly using my PowerBook within a few feet of the AE, I am getting some static, or little "pops" in the audio. What's weird is that I only get this static when I play certain songs, but the thing is that I know that these songs are flawless (because I plugged in a pair of headphones and checked to see whether or not my songs were poorly encoded, and they AAC files were fine). I made sure everything was securely plugged in, and that my computer was well within 50 feet of the base station. I connected the speakers to the PowerBook directly, and I didn't get any static, so I'm not sure what the problem is. Anyone have any ideas?
