Orangepi PC Plus mit PCM510A

[hajupiko49]

Good day,

for my Orangepi PC+ I installed Armbian Ubuntu Jammy on a µSD card. Up until Armbian Ubuntu Strech I was able to use a PCM510A for sound output. The settings for this were easy. With all updated OS after Strech, I can't install the PCM. Unfortunately, the help that was published in the forum wasn't helpful or I couldn't take it over. On the eMMC I have installed Armbian5.59 Orangepipcplus Ubuntu xenial default 3.4.113 desktop. Because of the advanced age of this OS, there are no updates and upgrades. Luckily my internet radio still works.

Can someone explain to me how I can install the PCM510A at Jammy?

Kind regards

No idea if this is possible with mainline if that needs vendor adjustments. Make sure to read here to understand why

@hajupiko49It should work!

Read this tread "https://forum.armbian.com/topic/9009-info-friendlyarm-pcm5102a-hat-with-nanopi-neo-under-mainline-4xx-and-dev-5xx/"

(Thanks Guido)

 

I dit it on a Orangepi-Plus with bullseye, kernel 5.15.

 

Use this steps:

sudo apt update && sudo apt upgrade -y
freeze updates in armbian-config dtb

 

Than you can begin changeing your dtb.

You have only to replace "sun8i-h3-orangepi-plus" to your needs..
