5454ty · ‎08-25-2024

Hi

My platform is imx93

Linux :6.1.22

I am debugging the wm8960 audio codec:

I running the command:aplay 1.wav

It has no sound and has no error

root@imx93evk:~# aplay 1.wav
Playing WAVE '1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo

My dts is as follows:

The whole dts ,and log is as follows:

Hello @5454ty

I hope you are doing well.

Please first check the audio devices on your board with command:

root@imx93evk:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: btscoaudio [bt-sco-audio], device 0: 443b0000.sai-bt-sco-pcm-wb bt-sco-pcm-wb-0 [443b0000.sai-bt-sco-pcm-wb bt-sco-pcm-wb-0]

root@imx93evk:~#

For i.MX93EVK the wm8962 is connected to jack J1201. and the command for reproduce the audio is:

root@imx93evk:~# aplay -D hw:3,0 piano2.wav 
Playing WAVE 'piano2.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Also, if you want change the default playback hardware you can modify the /etc/asound.conf as follow:

# Global alsa-lib configuration

pcm.!default {
    type hw
    card 3
}

ctl.!default {
    type hw
    card 3
}

I hope this can helps to you.

Best regards,

Salas.

HI，

I can play the music ,but i cann't play the music by recording

My command as follows:

Hello,

How are you recording the audio?

Do you have a specific device to do it? if yes, could you please share the log of command:

Maybe the file is not being recorded correctly and that is the reason that there is not audio.

In i.MX93EVK the audio is recorded by micfilaudio device.

Also, you can specify the frequency to record and playback.

Best regards,

Salas.
