piplayer

Linux only.

This allows a keyboard to control some mp3s in a directory. Why? So I can have a three-button keyboard connected to a raspi, and raspi connected to a speaker, and my 2 year old can push a button and play/pause/skip as she sees fit.

Do all this as root on a Pi 5 with headless raspberry pi debian:

• Use python 3.12
• pip install just_playback keyboard
• edit /etc/asound.conf to set your default device (look with aplay -l)
• Copy the service file into /etc/systemd/
• Enable & start the service

Example /etc/asound.conf

pcm.!default {
    type hw
    card "Device"
    device 0
}

ctl.!default {
    type hw
    card "Device"
}

This works for the USB device:

# aplay -l
