2) Through the aplay -l command, you can view the sound card devices supported by the Linux system

a. The output of the linux5.4 system is as follows, where card0:audiocodec is the sound card device required for earphone playback

root@orangepi:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: audiocodec [audiocodec], device 0: SUNXI-CODEC sun50iw9-codec-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

b. The output of the linux6. 1 system is as follows, where audiocodec is the sound card device required for earphone playback

root@orangepi:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: audiocodec [audiocodec], device 0: CDC PCM Codec-0 [CDC PCM Codec-0]
Subdevices: 1/1
Subdevice #0: subdevice #0

3) Then use the aplay command to play the audio, and the headset can hear the sound

root@orangepi:~# aplay -D hw:0,0 /usr/share/sounds/alsa/audio.wav
Playing WAVE 'audio.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

If there is noise in the earphone test, please pull out some earphones, do not insert all the earphones.

3.12.1.2 HDMI audio playback test

1) First use the Micro HDMI to HDMI cable to connect the Orange Pi development board to the TV (other HDMI monitors need to ensure that they can play audio)

2) HDMI audio playback does not require other settings, just use the aplay command to play directly

root@orangepi:~# aplay -D hw:2,0 /usr/share/sounds/alsa/audio.wav
