sudo apt remove pulseaudio*
sudo apt purge pulseaudio*

Jack Audio

TODO

• Installing jack with apt is buggy as all hell due to some problems with dbus, you should remove & purge the apt version and use the jackd_source script: python -m autopilot.setup.run_script jackd_source

HiFiBerry

If using HiFiBerry DAC+ ADC pro or HiFiBerry Amp2,

• Make sure you are not using any of the GPIO Pins as Digital_Outputs : 3, 5, 12, 35, 38, 40, 7
• Add pin 7 to the 'PULLUPS' Pref (pin 7 is a mute button)
