Good news for all you Linux and Apple's Airport Express lovers out there - if you've been looking for a way to stream sound wirelessly to your stereo speakers, there's finally an app that allows you to do so. It's called Pulseaudio, and while the name isn't as catchy as "AirTunes," it certainly matters not after you've got it all up and running within a few minutes.
Very much like Apple's patented AirTunes feature on the Airport Express, the idea is to get sound playing from your laptop/desktop across the room via your AE's audio-out jack. This eliminates the need to run a RCA cables from your computer's audio out (a.k.a. the "old school" way) and definitely frees up on clutter from having wires strung across the room.
MakeUseOf wrote up a pretty thorough step-by-step process on how to set up PulesAudio over at their blog. You basically just install the software (link here), change the output mode to your Airport Express, and you're immediately up and running.
If you're an owner of both a Linux computer and Apple's Airport Express and want to have your stereo speakers as your dedicated listening center, there's really no reason why you shouldn't check out the software.
Hopefully in the next few months we can see the wireless HDMI become a bit more mainstream so we can stream both HD video with sound across the network without anymore hiccups!
