Hi all,
I just installed alarm on my Rock64_V2, System works fine so far except there is no Audio neither on HMDI nor 3.5mm Jack.
Kernel: aarch64- Linux 5.7.8-1-ARCH
Gnome 3.36.4 (Wayland)
ALSA Driver Version k5.7.8-1-ARCH
Alsa-utils 1.2.3-2
Pulseaudio 13.0-3
Alsa does not detect any Sound Card and Gnome shows only Dummy Output as available Output Device.
Have I missed something?
I followed the wiki article on archlinuxarm.org for installing/setting up the basic system and then installed Wayland, Gnome, Alsa-Utils and PulseAudio was installed as a dependency. No further software installed except Firefox and System is up-to-date.
Rock64_V2 no audio, how to fix?

I found this on the Change Log for Kernel 5.5
$this->bbcode_second_pass_quote('', ' ')And finally rk3328 audio support, sdmmc detection fix and enabled
of the gpu on rk3399-puma.

$this->bbcode_second_pass_quote('', 'a')rm64: dts: rockchip: Add RK3328 audio pipelines
$this->bbcode_second_pass_code('', 'The audio pipelines for HDMI and the analog codec are internal to the
SoC, so it makes sense to describe them at that level such that boards
need only enable the respective nodes for outputs they implement.

How can this rk3328.dtsi file be used to fix Audio on the Rock64 or any other RK3328 based SBC ?
