After many hours trying to get wireless streaming from Spotify to Playstation 3, I finally found a working solution on Linux (ubuntu).
I used the solution described in this blog.
But I failed miserable with only streaming the echoes of silence...
Then I found another Spotify streaming blog post, only this time for squeezebox.
This inspired me to try the same trick creating a PulseAudio null-sink.
pactl load-module module-null-sink sink_name=spotify
Setting the sound output to the new sink:
install the lame encoding library to be able to stream mp3:
sudo aptitude install gstreamer10.0-plugins-ugly-multiverse
make sure icecast is running
and then fire up a mp3 stream:
gst-launch-0.10 pulsesrc device=spotify.monitor ! audioconvert ! lame bitrate=320 mode=stereo ! shout2send ip=localhost port=8000 password=PASSWORD mount=spotify.mp3
I then added the following line to my WEB.conf in the ps3mediaserver root folder:
Now start up your PS3 and PS3 Media Server. On your PS3 go to the 'Audio' section, select 'PS3 Media Server', Web-folder and Spotify. Be patient it takes a couple of seconds before it starts.
