Rock Pi 4c: no 3.5 jack audio on Armbian focal

[mkr]

Armbianmonitor:

My system has:

 

$uname -a 
Linux rkpi 5.8.11-rockchip64 #20.08.4 SMP PREEMPT Wed Sep 23 17:51:13 CEST 2020 aarch64 aarch64 aarch64 GNU/Linux

 

Sound stack seems to be loaded, but alsa/pulseaudio sees only hdmi-output device (aplay log below). How to enable analog ouput on 3.5 mm jack?

Hi

I have the same problem @

Linux rockpi-4c 5.8.13-rockchip64 #20.08.8 SMP PREEMPT Mon Oct 5 15:59:02 CEST 2020 aarch64 aarch64 aarch64 GNU/Linux

My experience shows that the original Radxa kernel 4.4.153 shows audio devices and the Alsamixer offers many options.
It would be very nice if the same behavior occurs in the armbian (without the old legacy kernel).

It is fixed in master as of https://github.com/armbian/build/commit/1c29779e573956461b985c03cd293f5cf6ae1609

It will be part of v20.11 release.

 

If you want it sooner... Put the following content into fix-es8316.dts file.

Spoiler

/dts-v1/;
/plugin/;

/ {
        compatible = "rockchip,rk3399";

        fragment@0 {
                target = <&i2s0_8ch_bus>;


                __overlay__ {
                        rockchip,pins =
                                <3 24 1 &pcfg_pull_none>,
                                <3 25 1 &pcfg_pull_none>,
                                <3 26 1 &pcfg_pull_none>,
                                <3 27 1 &pcfg_pull_none>,
                                <3 31 1 &pcfg_pull_none>;
                };
        };
};

 

Run "armbian-add-overlay fix-es8316.dts", reboot and enjoy!
