Cubieboard2 no sound - aplay: pcm_write:2165: write error

[jazzi]

Hello,

My Cubieboard2 has AllWinner A20 Soc which has no sound after system installation followed by the official guide here.

User alarm has been added to group `audio` and unmuted channels, no PulseAudio or PipeWire installed, pure ALSA.

Hereby is the errors:

$this->bbcode_second_pass_code('', '[alarm@alarm alsa]# aplay Noise.wav
Playing WAVE 'Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: pcm_write:2165: write error: Input/output error')

And some information may need:

$this->bbcode_second_pass_code('', '[alarm@alarm ~]$ cat /etc/group | grep audio
audio:x:996:alarm')

$this->bbcode_second_pass_code('', '[alarm@alarm ~]$ aplay -l

What I have tried:

1. Created ~/.asoundrc and add the following content

$this->bbcode_second_pass_quote('', 'd')efaults.pcm.card 0
defaults.ctl.card 0
