Prerequisites

Headless Raspberry Pi setup

Sound tests

List sound devices:

$ aplay -L

Play a sound on default RPI output:

$ aplay /usr/share/scratch/Media/Sounds/Vocals/Singer2.wav

Install a DAC

I bought this USB DAC but it is cheaper without the enclosure.

Play on USB DAC:

$ aplay -D default:CARD=DAC /usr/share/scratch/Media/Sounds/Vocals/Singer2.wav

Set USB DAC as default output:

$ sudo emacs /etc/modprobe.d/alsa-base.conf

Comment that line:

options snd-usb-audio index=-2

Add that line:

options snd-usb-audio nrpacks=1

Restart daemon:

$ sudo /etc/init.d/alsasound restart

Install squeezelite

I already have a Logitec Media Server installed on my NAS for my [Squeezebox Radio](http://en.wikipedia.org/wiki/Squeezebox(networkmusic_player). So let's install SqueezeLite client on the raspberry pi.

Install dependencies:

$ sudo apt-get install libflac-dev
$ sudo apt-get install libfaad2
$ sudo apt-get install libmad0

Install squeezelite:

$ mkdir squeezelite
$ cd squeezelite
$ wget http://squeezelite.googlecode.com/files/squeezelite-armv6hf
$ sudo mv squeezelite-armv6hf /usr/bin
$ chmod u+x /usr/bin/squeezelite-armv6hf

Test with:

$ squeezelite-armv6hf -l
$ squeezelite-armv6hf -o default:CARD=ALSA -a 200
$ squeezelite-armv6hf -n "PI-NAME" -a 200

Install daemon:

$ sudo wget http://www.gerrelt.nl/RaspberryPi/squeezelitehf.sh
$ sudo mv squeezelitehf.sh /etc/init.d/squeezelite
$ sudo chmod a+x /etc/init.d/squeezelite

Fix daemon script:

$ sudo emacs /etc/init.d/squeezelite

Remove 'SLMAC' stuff and set:

SLOPTIONS="-a 200 -n PI-NAME"

Start daemon:

$ sudo update-rc.d squeezelite defaults
$ sudo service squeezelite start

Install AirPlay

Now I want to stream the music stored on my NAS to the raspberry pi through Audio Station, controlling it with DS Audio.

Thanks to ShairPort that's easy.

Install dependencies:

$ sudo apt-get install git libao-dev libssl-dev libcrypt-openssl-rsa-perl libio-socket-inet6-perl libwww-perl avahi-utils
$ sudo cpan install Net::SDP

Install ShairPort:

$ git clone https://github.com/abrasive/shairport.git shairport
$ cd shairport
$ ./configure
$ make
$ sudo make install

Test:

$ shairport.pl -a ShairPort
