SpoCon is a Spotify Connect for Debian package and associated repository which thinly wraps the awesome librespot-java library by Gianluca Altomani and others. It works out of the box on all three revisions of the Pi, immediately after installation.

NEW: Spocon supports now also Docker, instructions are here: Spocon Docker

This command downloads and installs the Debian package and adds its apt repository, which ensures you'll always be up to date with upstream changes.

curl -sL https://spocon.github.io/spocon/install.sh | sh

That's it! Plug a speaker into your Pi on your local network, select the device in Spotify et voilà!

sudo add-apt-repository ppa:spocon/spocon
sudo apt-get -y update
sudo apt-get install spocon 

Essentially, here's what the easy installer does,

# Add repo and its GPG key
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7DBE8BF06EA39B78
## This downloads the armhf version for Raspbian Pi
echo 'deb http://ppa.launchpad.net/spocon/spocon/ubuntu bionic main' | sudo tee /etc/apt/sources.list.d/spocon.list

# Install package
sudo apt-get update
sudo apt-get -y install spocon

Some people report problems importing the key for our repository. If the above command fails due to the keyserver, you can try the following beforehand:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 7DBE8BF06EA39B78

You'll need a Spotify Premium account in order to use Connect.

To uninstall, remove the package,

sudo apt-get remove -y spocon

To completely remove spocon and its Debian repository from your system try,

sudo apt-get remove -y --purge spocon

SpoCon should work out of the box and should be discoverable by Spotify Connect on your local network, however you can configure it by editing /opt/spocon/config.toml which passes arguments to librespot-java.

If you have a firewall, you need to open the UDP port 5355 for mDNS. Then specify some random port in zeroconf.listenPort and open that TCP port too.

After editing restart the daemon by running: sudo systemctl restart spocon

• Vagrant installed ( https://www.vagrantup.com/ )
• Virtualbox installed ( https://www.virtualbox.org/wiki/Downloads )

cd Vagrant
vagrant up # start your environment
vagrant ssh # login into you environment
cd workspace
ansible-playbook Ansible/start.yml -e librespot_version=0.5.2 -e spocon_version=0.14.0

There should be a built Debian package (a .deb file) in your project directory /package.

My volume on Spotify is 100% and it's still too quiet!

Have you tried turning the volume up using the command alsamixer?

My Raspberry Pi does not use my USB sound card!

Check with aplay -l as which card your USB device is listed. Let's say it is "card 1", so try to replace the following in the file /usr/share/alsa/alsa.conf:

defaults.ctl.card 0
defaults.pcm.card 0

with

defaults.ctl.card 1
defaults.pcm.card 1

The audio output buzzes a few seconds after audio stops!

This is likely to be ALSA's Dynamic Audio Power Management (DAPM) shutting down the sound module of your device to save power. If you want to disable this feature, create a file called snd_soc_core.conf in /etc/modprobe.d with this line in:

options snd_soc_core pmdown_time -1

Once you reboot and play some sound, the issue should be gone.

Other issues

File an issue and if we get it sorted, I'll add to this list.

(I'd rather you donate to librespot-java instead, but there's no public address for those folks.)
