rock64 - No 3.5mm audio

[wolt]

Hi all,

I'm unable to get audio out of the 3.5mm audio jack on my rock64.

I came upon another (locked) thread of someone with the same issue here, which unfortunately lead to a dead end.

$this->bbcode_second_pass_code('', '
$ dmesg | grep -i alsa -A 1
[ 6.051209] ALSA device list:
[ 6.051481] No soundcards found.
')

$this->bbcode_second_pass_code('', '
$ ls /dev/snd
seq timer
')

$this->bbcode_second_pass_code('', '
$ sudo aplay -l
aplay: device_list:272: no soundcards found...
')

Currently running kernel 5.3.7-1-ARCH.

If I were to take a shot in the dark I wouid guess that the rk3328-rock64.dtb is missing the required bits for this to work, but this is very much not my area of expertise, so any help in understanding the problem/working to find a solution is greatly appreciated!
