SOUND not working on im8qxp-mek with imx-aud-io attached

[carlo_p]

Hi,

I have im8qxp-mek (REV C1) and and trying to play some audio through sound card imx-aud-io with no results.

I'm working with the "wayland / imx-image-full".

I've connected imx-aud-io to the baseboard board, using AUDIO SLOT 1. I've learned that the correct codec to use is CS42888, in order to play audio on the sound card.

During boot, I read this:

3.344040] debugfs: Directory '59050000.sai' with parent 'wm8960-audio' already present!
[ 3.351309] imx6q-pcie 5f010000.pcie: IO 0x7ff80000..0x7ff8ffff -> 0x00000000

[ 3.667255] cs42xx8: probe of 5-0048 failed with error -1

According to this, when I execute aplay -L, I get:

null
Discard all samples (playback) or generate zero samples (capture)
pulse
PulseAudio Sound Server
sysdefault:CARD=imxaudmix
imx-audmix,
Default Audio Device
sysdefault:CARD=btscoaudio
bt-sco-audio,
Default Audio Device
sysdefault:CARD=wm8960audio
wm8960-audio,
Default Audio Device

Also, I can correctly play audio using wm8960 codec.

Do you have any ideas? Am I missing something?

did you try the mek base board? as I known, if iMX8QXP + mek base board, the default sound card is cs42888

Could anyone (maybe from the support) help me, please?

From the log,

[ 3.661204] cs42xx8 5-0048: failed to get device ID, ret = -1
[ 3.667255] cs42xx8: probe of 5-0048 failed with error -1

Not able to detect the CS42xx8, Please check I2C node port/pin mux configuration, in the dts file

and use I2Ctool to verify it from user space, On which I2C port you will get the CS42xx8 (address:0x48)
