No soundcards found in ALSA device list

[simonlin]

Hi  NXP

Here's my environment

SoC:imx8qm

audio chip:add2010

OS:yocto kirkstone

Linux version:5.15.71

It show No soundcards found in ALSA device list

But I cat /proc/asound/cards, the add2010 audio is registered successful

I try to play audio file, and control audio volume are OK

I don't understand why it show No soundcards found in boot log

Do not worry about it, I have test on our EVK BOARD, found the No sound cards found the same. Because not sound card are in using, I think it is the reason. The same with you, it is not the error or failed information, you can ignore it.

But in your log you can see it is already added success.

You can also see that all the sound card support in my side:

So it is OK in your side, no problem.

Are you using NXP reference board or the board you designed yourself?

Hi @Rita_Wang 

We are using the board designed by ourselves

Do you have any suggestion?

Thanks
