But there is no added sound card "sndrpisimplecar".

  ```
pi@raspberrypi:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
card 1: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]
 Subdevices: 1/1
 Subdevice #0: subdevice #0
```

I already checked the sound card "sndrpisimplecar" was added well in Raspberry Pi 3 at card 1 .
But in Raspberry Pi 4 it doesn't work.
There is a difference that Hdmi sound card number between Pi 3 and 4, pi 3 have only card 0 : for hdmi.
i am not sure it is the reason.

Thanks if you can advise me how to solve this problem.

@LucianoMartin, please provide a Story Point value for this issue. Thanks.

Hi @jason-sepion, thanks for reporting this issue. We have recently updated the procedure to configure the RaspberryPi. Can you please retry using the instructions in the README.md at the head of master or from the v5.8.0 release.

If this doesn't work, can you please let us know if the .asoundrc file is copied to the home directory?

[jason-sepion]

@LucianoMartin I will follow the instructions and let you know the results right away. It may take several days. Thank you for supports.

I am also running into this same issue, even when following the new v5.8.0 release. Has a solution been found for this? And will the KBUILD_OUTPUT message affect the vocal fusion setup?

[mbanth]

Thanks, @jaritondo, for your question. We will have one of our customer engineers look into the setup using v5.8.0 on a Raspberry Pi 4.

@jason-sepion we have a new release which should have fixed a lot of the issues we were seeing with missing sound cards. If this is still a problem, please give it a try and let us know if your issue persists.
