May 24, 20251 yr Hello,  With kernel 6.6.56-current-rockchip64 the audio works correctly: cat /proc/asound/cards  0 [RK809         ]: simple-card - Analog RK809                      Analog RK809  1 [HDMI          ]: simple-card - HDMI                      HDMI  With kernel 6.12.30-current-rockchip64 the RK809 card is not available: cat /proc/asound/cards  0 [HDMI          ]: simple-card - HDMI                      HDMI  How can this be solved ? Thank you so much !
May 26, 20251 yr I am not very familiar with Radxa and Rock. But I cannot find the board among those supported by armbian. Let me ask you where you got your image and kernel?
May 27, 20251 yr Author Hi !  I got the Bookworm minimal image here: https://www.armbian.com/cf7stdb-entries/rock-3c/ Armbian_community_25.8.0-trunk.38_Rock-3c_bookworm_current_6.12.30_minimal.img.xz  I think I could try getting the image here too: https://armbian.atomonetworks.com/dl/rock-3c/archive/ Armbian_25.2.1_Rock-3c_bookworm_current_6.12.13_minimal.img.xz
May 27, 20251 yr I'd probably start with comparion the device trees of both images and check for altered/removed nodes related to audio.
May 27, 20251 yr Author I tried the image from "armbian.atomonetworks.com" and the exact same thing happens. Thanks, I'll compare the images.
July 25, 20251 yr hi, not sure for the sbc, but on uefi-x86, alsa has hdmi audio, but its not loaded for pulseaudio ... ?? here I managed to load it and unmute SPDIF in alsamixer (I still dont understand how devicetree powered SBCs differ against uefi-x86 system ... excuse me)  crucial help from Lyra 🙂 ... unmuting SPDIF did the thing, probably also loading the sink also, ufff https://chatgpt.com/share/68836e5f-9e4c-8000-8874-46ea35a07331
