raspberry pi volumio 9018k2m trick
Volumio 1.4, 1.5 and 1.51 needs to be tricked to play music through the ES9018K2M. If you select a generic DAC driver, you cannot use it for audio output directly using the GUI.

failed to open vchiq instance raspbian volumio
If you get an error like “failed to open vchiq instance” you’ll need to do as root:
echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules
usermod -a -G video [your_username]
- Or as one time temporary solution (until reboot):
chmod a+rw /dev/vchiq

Getting a Python script to run in the background (as a service) on boot
For some of my projects I write a simple service in Python and need it to start running in the background when the Raspberry Pi boots. Different Linux distributions use different ways of starting and stopping services (some now use Upstart, some systemd). I am using the “Wheezy” Debian distribution on my Raspberry Pi, and in this case the proper way to do this is using an “init script”. These are stored in the /etc/init.d folder. In there you can find scripts that for instance, start the networking system or a print server. Debian Wheezy uses the old Sys V init system which means that these scripts are run according to symbolic links in the /etc/rc.x directories. The Debian documentationexplains this. Continue reading Getting a Python script to run in the background (as a service) on boot
I²S Audio Support for Raspberry Pi
You might know, that the audio capabilities of the Raspberry Pi are not very sophisticated. There is no special audio hardware, because this would have risen the price of the Raspberry Pi. Therefore, there is only audio output via PWM and no audio input. Fortunately, the Revision 2 Raspberry Pi features I²S via an additional GPIO port. Continue reading I²S Audio Support for Raspberry Pi
