amixer doesn't show any controls on the first card (and so does alsamixer) - amixer -c 0 shows nothing, while amixer -c 1 has a lot of output, but I think it's just showing the controls for the rockchipes8388 audio card (the analog output, not the HDMI).

I have an Orange Pi 5 board, installed with the 25.8 Debian Bookworm + Cinnamon desktop system. I have switched (using armbian-config) to the edge kernel in order to test the HDMI audio support in the new Linux kernel, but I'm not getting any audio out. The ALSA HDMI card seems to be present (see below), but there's no sound using speaker-test or aplay. I have enabled the hdmirx overlay through armbian-config also, but the result is the same. Is there anything extra that should be configured in order to get audio output ? Output from armbianmonitor - https://paste.armbian.com/gegorimako

Hello @Igor, thank you for the update. I understand the predicament for lacking enough resources given the scope of the project and I don't expect things to work OOB without testing. I've updated the package list via apt and now I can see the headers package now for the current-rockchip-rk3588 Linux kernel (along with a the new linux-image .deb package). I have installed it and can confirm that dkms works fine to complile the WiFi dongle's driver - though it's not fully working yet, though this is purely a driver issue, not related to Armbian/Debian. Thanks for the updated kernel packages.

@Werner thank you for the reply. I'm familiar with the Wiki page, I'm aware some functionality will be missing using the 'edge/current' kernels. In fact, my intention when using the current/upstream kernel was to test how HDMI output was working, since it wasn't working a few months back. However, the functionality I'm missing is not related to the specific SBC/Vendor - as you said also, I was expecting the driver for the 8812au to be included/work. I haven't found a related 'kernel headers' package through apt also, hence my question/topic is mostly about the package. Having the headers package would help with any external kernel module that would be installed through dkms.

I have installed the recently released `Desktop images with Armbian Linux v6.10` image (24.8.1, Debian Bookworm, with the Cinnamon desktop) on an OrangePi5 and I'm happy the HDMI support included has finaly enabled the video to my 1080p display. However, my previously supported WiFi adapter is not recognized in this version - it worked with the vendor (5.10) kernel which I used with last year's OrangePi5 image, but how it seems the driver is not installed with 6.10. The WiFi adapter is connected via USB and it's listed as Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter. Now, there are a few DKMS/out-of-tree drivers that I could install, but the problem is that there are no kernel headers for the current Linux image kernel - trying to install them via armbian-config returns me to the previous screen almost immediately. Is the kernel headers package missing or is maybe named differently ? FWIW, the Linux image package is linux-image-current-rockchip-rk3588.
