Volumio setup for the Octo (without building)

[flatmax]

This post will tell you how to install volumio on a Pi for the Audio Injector Octo 8 channel card.

Firstly download the volumio image and extract it, then write it to an SDCARD, you can get it here.

Now insert that card into your Pi and wait something like 5 minutes. Next enable ssh so that you can setup the audio driver. To enable ssh, go http://volumio.local/DEV/ in your browser and click "ENABLE" under SSH. It doesn't report anything but you have just enabled the SSHd daemon. You can now login to your volumio device.

Open a terminal and tell ssh to connect to the Pi like so :

Code: Select all

ssh volumio@volumio.local

The password is volumio

Setup the /boot/config.txt file by editing it as super user (password is volumio) :

Code: Select all

sudo nano /boot/config.txt

Adding this line to the /boot/config.txt file (I put mine at the end of the file) :

Code: Select all

dtoverlay=audioinjector-addons

Also comment out the lines which relate to the onboard Pi PWM audio system :

Code: Select all

#dtparam=audio=on
#audio_pwm_mode=2

The /boot/config.txt file looks something like this now :

Code: Select all

initramfs volumio.initrd
gpu_mem=16
max_usb_current=1
#dtparam=audio=on
#audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
dtoverlay=audioinjector-addons

Now reboot :

Code: Select all

sudo reboot

At this point you can log back in and check the card is enabled like so :

Code: Select all

volumio@volumio:~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: audioinjectoroc [audioinjector-octo-soundcard], device 0: AudioInject-HIFI cs42448-0 []
  Subdevices: 1/1
  Subdevice #0: subdevice #0

That is it !
It should be working.

It's working for me but just with one channel!

I tried with and withoud /etc/asound.conf like from here
https://github.com/Audio-Injector/Octo


does not make any difference
my goal is to create a 5.1 setup to play 5.1 flacs

volumio@volumio:~$ aplay -L
