Yet another "how to make a Sam Aaron project on the current ubuntu version"
first add the following two lines at the end of /etc/apt/sources.list:
deb http://ppa.launchpad.net/sonic-pi/ppa/ubuntu xenial main deb-src http://ppa.launchpad.net/sonic-pi/ppa/ubuntu xenial main
sudo apt update
Install Sonic Pi:
sudo apt install sonic-pi
We need to kill pulseaudio and start jack, it sounds easier than it is because pulseaudio just won't stay dead :(
The way I found to make it work was to edit pulseadio client.conf:
sudo vim /etc/pulse/client.conf
Uncomment the line (remove the semicolon):
; autospawn = yes
And leaving it like this:
autospawn = no
I added myself to the audio group, not sure if it's required but just in case:
sudo adduser $USER audio
For this to take effect you need to logout and login again, to make sure you have the group, open a terminal and run:
You should see audio between some other groups, if you can't see it try rebooting or replacing $USER with your actual username in the adduser command.
Now stop pulseaudio:
Then start jackd, I tried all the combinations I could find on the internet without success, this is the one that worked for me:
jackd -R -d alsa -d hw:1
If that doesn't work try:
jackd -R -d alsa
Or try the versions that are recommended on the overtone wiki:
jackd -r -d alsa -r 44100
jackd -r -d alsa -r 44100 -P
You can also try running qjackctl and play with the settings to see if you have luck.
If that doesn't work read /usr/share/doc/sonic-pi/README-JACKD to see if the instructions there help.
Now you should be able to run sonic-pi:
