Radxa Zero > Hardware > Audio
USB Audio
Due to space constraint, Radxa Zero does not have a 3.5mm headphone jack for audio output. To get audio output from Radxa Zero, the easiest way is to connect to a HDMI soundbar*. Alternatively you can connect to a USB sound card. Or even better, a USB speaker, which has integrated USB sound card inside. In this guide we will show you how to play sound on your USB speaker using Radxa Zero.
Note: currently the HDMI audio is not working out-of-box on our official image. You will need to manually install this package to have it working. We will add it to our official image in a later time once we know the package won't negatively affect existing users.
Please connect your hardware in following way:
Type-A USB speaker --- Type-C to Type-A USB Hub --- Radxa Zero
In a terminal window on Zero, we will first run aplay -l to check card id for our USB speaker.
root@zero:/home/rock# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: RADXAZERO [RADXA-ZERO], device 0: fe.dai-link-0 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: RADXAZERO [RADXA-ZERO], device 1: fe.dai-link-1 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: RADXAZERO [RADXA-ZERO], device 2: fe.dai-link-2 (*) [] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: CD002 [CD002], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0
Once you identify your USB speaker, edit /etc/asound.conf to set it as the default output:
root@zero:/home/rock# cat /etc/asound.conf
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
You can now test your speaker by playing some sound with mplay or aplay:
root@zero:/home/rock# mplay test.wav
or
root@zero:/home/rock# aplay -Dhw:1,0 test.wav
