Recently some friends and me were talking about streaming music from iTunes to my dockstar with an usb sound device connected. I knew there is a solution, so I started some research an found shairport at mafipulation.org. The project looks quite interesting and I tried to set everything up that I am able to play my music remotely.
First there are some dependencies you need to install:
apt-get install build-essential libssl-dev libcrypt-openssl-rsa-perl libao-dev libio-socket-inet6-perl libwww-perl avahi-utils pkg-config
Now all you need to do is download the sources, make and install them: Get the sources at github.com/albertz/shairport/downloads.
Untar them and navigate into the extracted directory. Now start make:
make
If this is done, test it:
perl shairport.pl
You should be able to select the shairport server in iTunes. If you now play music it should stream to your dockstar.
If you want to install shairport as a service type:
make install
cp shairport.init.sample /etc/init.d/shairport
insserv shairport
/etc/init.d/shairport start
