Stream audio (Spotify) to Volumio

Hey,

I have two usage szenarios for my Volumio:

  1. listen to webradio, works perfectly
  2. stream my audio output from my computer/laptop running Ubuntu to Volumio, so that I can listen to my free Spotify, doesn’t work

I tried with installing shairport on my laptop, but propably due to a bug (see: raop2 and UDP) it doesn’t play.

Is there another option how I can stream the output of my soundcard (using pulseaudio) to my Volumio running on my Raspberry Pi?

Thank you for your help in advance.

Timo
