Internet Radio with an Orange PI Zero

1 Comment

I had build an Internet Radio with an ESP32 and a VS1051 MP3 decoder, but I was not happy with the sound quality. So I am now trying it with a Orange PI Zero board and an USB DAC.

USB Sound DAC for Internet Radio

Currently I have an USB headphone connected to the PI, but I have ordered a Lusya SA9023A + ES9018K2M USB Portable DAC HIFI External Audio Card Decoder from Aliexpress.

On the Orange PI Zero I installed MPD and MPC for the sound deamon and the controller.

apt install mpd mpc

I also installed apache2 and php to run the web based front end from.

apt install apache2 php
orange-pi-zero

The Orange PI Zero is an Older SOC with WiFi and an USB port, just the things you need for this project. You can buy it for around 18 Euro from Aliexpress.

Plug  your USB DAC in the Orange PI Zero and check the card id.

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 1: Headset [Logitech USB Headset], device 0: USB Audio [USB Audio]
Subdevices: 0/1
Subdevice #0: subdevice #0

Here it shows that your hardware card ID = 1.
Use this number to edit /etc/mpd.conf and scroll down to the audio_output section. Here you can change the line with device from hw:0,0 to the below :

audio_output {
type "alsa"
name "My ALSA Device"
device "hw:1,0"
}

After making changes to mpd.conf you will need to restart mpd

service mpd stop
service mpd start

To add Internet Radio station use the following command:

mpc add http://airspectrum.cdnstream1.com:8114/1648_128

You can add as many stations you want with the above command.

mpc -f "%file%" playlist

To list all the radio stations you added with the mpc add command.

For the web frontend I combined two setups into my setup.
The two sources are:

When trying to copy some data (About 25Mb) the connection over the WiFi , it suddenly stopped. When using the fixed Ethernet the problem does not show.  When using the WiFi without big data transfers the problem also does not show. Even not when running for a longer time with total more then 50Mb.
