NanoPC-T4 can't produce sound

[bls]

Hi!
I have a problem with sound with my T4. In a nutshell: there is no sound neither via Jack, nor via HDMI.

I've installed FriendlyDesktop (bionic-4.4-arm64-20181112). So my configuration is:

Code: Select all

$ uname -a
Linux NanoPC-T4 4.4.143 #1 SMP Mon Nov 5 16:42:17 CST 2018 aarch64 aarch64 aarch64 GNU/Linux

Code: Select all

$ aplay -l
aplay: device_list:270: no soundcards found...

Code: Select all

$ cat /proc/asound/cards
 0 [realtekrt5651co]: realtek_rt5651- - realtek,rt5651-codec
                      realtek,rt5651-codec
 1 [rockchiphdmi   ]: rockchip_hdmi - rockchip,hdmi
                      rockchip,hdmi
 2 [ROCKCHIPSPDIF  ]: ROCKCHIP_SPDIF - ROCKCHIP,SPDIF
                      ROCKCHIP,SPDIF

Code: Select all

$ lspci

(doesn't show anything at all)

Code: Select all

$ lsmod
Module                  Size  Used by

(also no useful output)


I guess I do have soundcard, but it's something like "disabled" How it can be repaired?

I've finally found the solution: it is simply have to be changed the output device in vlc or pulseaudio utility.
