audio play error!!

[aron]

Hi.

A problem occurred while running STMP1-SOM.

Audio play does not work.
Do you have any idea how to fix this?

console message:

Audio play back should work in the official images. Both aplay and mplayer should work, maybe try mplayer sign_return.wav

Try another format or audio file. Edit the settings in alsamixer maybe, sometimes channels can be muted and some terminals make it hard to notice that these channels are muted. Try to unmute with "m" key.

Hi.
Try again with "STM32MP1-OLinuXino-SOM-bullseye-minimal-20220928-143706.img" for the image.

But I got apply error on "ASoC: error at snd_soc_dai_set_sysclk on es8328-hifi-analog: -22".

I think the reason for this error is the kernel driver.

[aron]

Audio play was successful by modifying the es8328 driver code.

There is a problem with the kernel driver on the site below, so please modify it and use it.

Thank you for the update, glad you got it figured out but can you be more specific about how you fixed this issue?

What was wrong wit the es8328 driver code? Your link point to a directory with many sub-folders.

Hello Team,

I just bought the "STMP157-BASE-SOM-EVB" and I, unfortunately, face the same issue as above when I am trying to play a MP3. I tried both images, full and minimal, but without success.

Has somebody found the issue in the ES8388 driver or is there another solution to this problem?

I guess the alsamixer settings are not alright. Some of the channels are initially muted (like the volume was up but the whole channel was muted). You can change whether it is muted or unmuted with key "M" on the keyboard. Each mixer should have "OO" at the bottom if it says "MM" it is muted. However, I have a suggestion - for terminal use TeraTerm, alsamixer gets visualized much better with TaraTerm.

See how it looks here:

This is what my asound.state looks like:

I was able to get both my wav playing with:

aplay test.wav

and mp3 with mplayer with:

mplayer test.mp3
