Hi all, Well, I finally figured this out! Turns out it was not a PulseAudio problem but my home network configuration. I unknowingly had DCHPD running on my Linux laptop, which seemed to override the Airport's IP address with a 165.254.* one. Disabling the daemon and rebooting routers resulted in a normal 192.168.0.* address for my Airport, and I can enjoy music through it from Linux - finally! Thanks to Tanu and Colin for your help.
