The steps I've taken to setup my Raspberry Pi. My entrie setup flow is headless (connecting to the Pi over ssh on a local network), and on Mac OS X (which possibly matters for some stages). YMMV.

Raspian Image

• Download the latest "lite" Raspbian image from here.
• Connect your flash card to the computer you are working on
• Run the following commands from the terminal (last command takes around 5-10 minutes to complete for me... be patient)

# get the disk name from this command, e.g.: disk3
diskutil list

# then unmount the disk
diskutil unmountDisk /dev/{DISK#}

# then write the image to the disk
sudo dd bs=1m if=/path/to/raspbian.img of=/dev/{DISK#}

Connect

Now, plug the flash drive into the Pi, and connect the Pi to the local network with a network cable.

We need to find where the Pi is on our local network.

$ arp -na | grep -i b8:27:eb

Mine is currently at 10.0.0.3.

ssh pi@<IPADDRESS>
# then answer yes to the security question
# then login with the `raspberry` password

Config and Upgrade

sudo raspi-config
# do expand filesystem
# go to advanced options and then add a hostname
# finish and reboot, then log in again
sudo apt-get update && sudo apt-get upgrade
# there will be prompts, answer `y` to them

Install software

sudo apt-get install build-essential git emacs python-dev python-pip supervisor
sudo pip install jupyter jupyter-console ipdb

Install pyo

sudo apt-get install libjack-jackd2-dev libportmidi-dev portaudio19-dev liblo-dev libsndfile-dev python-dev python-tk python-imaging-tk python-wxgtk3.0 jackd2
git clone https://github.com/belangeo/pyo.git
cd pyo
sudo python setup.py install --install-layout=deb --use-jack --use-double

Using prebuilt Jack does not work, as it is compiled with dbus support, which in turn requires X, and I'm running headless (Raspian Lite) without X and similar libs installed. So, instead, I compiled Jack:

git clone https://github.com/jackaudio/jack2.git
cd jack2
./waf configure
./waf
./waf install

Thanks so much for this - incredibly helpful!
I have jack2 installed on a RPi 3, running headless on Raspian Lite. Jack is not throwing any dbus errors, however it is still not working! When I enter:
jackd -P75 -dalsa -dhw:0 -p1024 -n3 -s -r44100 &

I get the following:

After this it simply hangs. Any ideas?

Thanks for any suggestions!

Also interested in this. Following steps now, will update soon with results.
