There are several options for the software to use. I tested some of them:
minidlnaThis small UPnP and DLNA capable server is part of the Raspbian "wheezy" distribution. You may install it with the standard procedure
sudo apt-get install minidlna
and edit the file /etc/minidlna.conf according to your needs.
The server is working quite good with UPnP capable software and devices like the SoundBridge, but my experience was not the best. In particular the Search function is not working.
Firefly (daapd)The firefly media server provides a much better integration with the SoundBridge. Raspbian even contains the package forked-daapd which contains a fork of the firefly server. But I didn't managed this one to function at the Raspberry Pi.
So I went back to good old mt-daapd which is another fork of Firefly. Unfortunately it is no longer part of the actual Debian or Raspbian repositories. But the source package is still available at the Ubuntu archive. I built a Debian package for Raspbian "wheezy" from it:
After download you may install it with:
sudo dpkg -i mt-daapd_0.9~r1696.dfsg-15build1_armhf.deb
sudo apt-get install -f
The first dpkg command will probably complain about unresolved dependencies, but the second apt-get fixes this.
You should edit /etc/mt-daapd.conf to adapt the path to the music collection and restart mt-daapd with
sudo /etc/init.d/mt-daapd restart
This solution is working very well together with the SoundBridge. Actually I'm running both mt-daapd and minidlna in parallel at the same Raspberry Pi. The first one is serving two SoundBridges, while minidlna allows to access the music collection at a Samsung TV.
