=== USB Audio ===

Equipped with one USB speaker device, Radxa Zero can output sound.

Let's take playing a song as an example.

This is the hardware connection

<pre>
Type-A USB speaker --- Type-C to Type-A USB Hub --- Radxa Zero
</pre>

Firstly use command, aplay -l, to check the audio card number. Here is card 1.

<pre>
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 1: CD002 [CD002], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
</pre>

Secondly create file /etc/asound.conf and add the following content.

<pre>
root@zero:/home/rock# cat /etc/asound.conf
pcm.!default {
type hw
card 1
}

ctl.!default {
type hw
card 1
}
</pre>

Finally use mplayer or aplay to play songs.

<pre>
root@zero:/home/rock# mplay test.wav
</pre>
or
<pre>
root@zero:/home/rock# aplay -Dhw:1,0 test.wav
</pre>
