Do you have issues with audio output? My Rock Pi 4C+ does not recognize builtin sound card: root@rockpi-4cplus:~# aplay -l **** List of PLAYBACK Hardware Devices **** root@rockpi-4cplus:~#

Looks like my Rock Pi 4C+ does not recognize builtin sound card: root@rockpi-4cplus:~# aplay -l **** List of PLAYBACK Hardware Devices **** root@rockpi-4cplus:~# armbianmonitor link: https://paste.armbian.com/xucibilaza It seems to me that there are some clues here: What is the issue? How can I fix it?

Thank you @atone for sending links, I will check them. Looks like it's related to custom Armbian build creation. I don't want to dig into it right now, because I'm not familiar with those processes and it will take some time to learn. Looks like editing armbian_firstlogin works for me currently.

I have same issues setting correct resolution on 5 inch 800x480 screen. I found a workaround in this this topic: Maybe someone knows better solution how to fix detection and setting proper resolution automatically? EDID seems to be right, because it worked on previous OS.

Thanks for posting this, it actually worked for me with 800x480 resolution, but my screen looks ugly and with bunch of waves... Did I missed some numbers?

Thank you! I still need to figure out more dynamic fix, because we need to support different screens and I want them to work automatically

We have automated process of building images and if some new package is necessary we adjust our build process. I think it's more convenient.

Hi I want to modify base armbian image using choot in order to install necessary software. I am also creating user during that process. My question is how can I skip or prefill the form that appears on first run? (user creation, time zone setting etc.) I was surfing the forum and found this answer. So, I came up with few options: 1) It looks like I can prefill my desired values for the form in "/usr/lib/armbian/armbian_firstlogin" file by editing it during chroot 2) I can remove user input parts in "/usr/lib/armbian/armbian_firstlogin", but preserve other important lines, since user will be created during chroot Is this valid options or there is more proper way to do this?

I am working with Rock Pi 4B+ and using image for Rock Pi 4B. Everything works like a charm. Thanks to Armbian team.

I was able to fix the issue with the help of this topic, in case anyone searching I am also experiencing problems surfing Armbian website here. I tried to look for Rock Pi 4 B images and also for the archive. It also redirected me to "mirror.yandex.ru". Today I could access these pages, because I was redirected to another source.

Hi, I am facing the same issue. I am from Ukraine and our government blocked russian services for reasonable reason. I've read, that one of the sources redirecting me to this blocked mirror and I couldn't do anything with it on my side. Is it true?
