Quick Install
There is an easy way to install support for DACBerry AMP/AMP+ on Raspbian Jessie.
Just run the following code from your Raspberry Pi with Internet connectivity:
curl https://www.osaelectronics.com/get/dbamp | bash
You may need to reboot once. After rebooting, everything should work!
*NOTE: If quick install doesn’t work at all, or want to follow step by step instructions, please refer to the Retropie part.
Volumio Instructions
Volumio team is already working to add official support on next release, but meanwhile, you can follow these steps to make it work:
*IMPORTANT: In order to make it works properly, is recommended to do a fresh install of Volumio and use lastest version.
Airplay
Volumio is a perfect choice if you want to stream music from your Apple devices.
Step 1
Open Volumio and navigate trought “Network” in Settings Panel, and connect to your WiFi network.
Step 2
Inside “Network” settings, locate “Hotspot Settings” tab and enable it if it’s not. Restart.
Step 3
Go to your desired Apple (or Windows) device and open iTunes if you are using a computer, or open the “control center” if using a phone/tablet. Go to the “Airplay” icon and select “Volumio”.
Step 4
That’s it! Enjoy streaming music!
Adding password to your Airplay device
With the Airplay feature activated, everybody will have access to your device and will be able to play music on it. If you want to add a password to it, follow these instructions.
Step 1
Open an SSH connection to your Pi, if you can’t connect at all, enable it on volumio.local/dev.
Then, type the following line to open up the template for the shairport config file in a text editor:
sudo nano /volumio/app/plugins/music_service/airplay_emulation/shairport-sync.conf.tmpl
Step 2
In the “general” section, add a password, like this:
general =
{
name = "${name}";
log_verbosity = 0;
password = "<your airplay password here>";
};
Save the file as usual and reboot.
Step 3
Connect to your device, you should be prompted for a password when airplaying to it.
Retropie Instructions
As for Raspbian Jessie, just run the following code from your Raspberry Pi with Internet connectivity:
curl https://www.osaelectronics.com/get/dbamp | bash
The next step is to edit the raspi modules list with:
sudo nano /etc/asound.conf
This file should be blank! Just copy and paste the following text into the file:
pcm.dacberry {
type softvol
slave.pcm "plughw:0"
control.name "PCM"
control.card 0
}
pcm.!default {
type plug
slave.pcm "dacberry"
}
ctl.!default {
type hw
card 0
}
Save the file as usual and reboot:
sudo reboot
Now to check everything is as expected, just type:
amixer aplay -l
You should see something like that:
pi@retropie:~ $ amixer Simple mixer control 'PCM',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 255 Front Left: 255 [100%] Front Right: 255 [100%] Simple mixer control 'PCM',0 Capabilities: volume Playback channels: Front Left - Front Right Capture channels: Front Left - Front Right Limits: 0 - 255 Front Left: 255 [100%] Front Right: 255 [100%] pi@retropie:~ $ pi@retropie:~ $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: sndrpihifiberry [snd_rpi_hifiberry_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [ ] Subdevices: 0/1 Subdevice #0: subdevice #0 pi@retropie:~ $
And voilà! Enjoy playing retro games!
