'Twas brillig, and Aditya Rajgarhia at 25/05/11 19:34 did gyre and gimble:

In theory this works, tho' I've not really had massive success with it

In paprefs you should see DLNA support (perhaps it's labelled as rygel.
It is via rygel that we support exporting the audio of your laptop as
DNLA streams. It requires that you manually load
module-http-protocol-tcp (pactl load-module module-http-protocol-tcp)
and making sure the firewall is open on it's port (4714 or 4715 IIRC,
but please check with netstat -ltp :))

Personally I didn't get it working on my PS3 but haven't had a place
since some extra patches went in... till give it a bash over the weekend.

As the author of the Airtunes support in PA I will admit it's still
kinda lacking. The timing is all a bit messed up and it really needs
some love. Now that we support passthrough, we'll have to have a look at
getting MP3 support included too, but that really does require us to
tidy up the protocol support first (which is pretty hard).

So in short, it's not likely to be a great option but if you can't get
the DLNA working, then it might work OK for you.
