Hi all, after installing the latest version of Armbian (Jammy 6.1.11 desktop) I found that HDMI monitor audio is not working. With the Ubuntu MATE version of odroid the audio worked. Armbian seems more powerful and its look is much better than MATE, I hope I can solve all the problems because I don't want to go back to MATE anymore, How can I make HDMI audio work? Thanks in advance...

 

PS. I have already updated the firmware to full with the WiFi USB stick problem which has since been resolved

Hi, try running the script for the 3.5mm jack and also 

 

amixer -c 0 set 'TOHDMITX I2S SRC' 'I2S B'

 

I think that has sorted HDMI for me.... I'm trying to get SPDIF working.

HDMI

sudo amixer -c 0 set 'TOHDMITX' 'on'
sudo amixer -c 0 set 'TOHDMITX I2S SRC' 'I2S B'
sudo amixer -c 0 set 'TDMOUT_B SRC SEL' 'IN 0'
sudo amixer -c 0 set 'FRDDR_A SRC 2 EN' 'on'
sudo amixer -c 0 set 'FRDDR_A SINK 1 SEL' 'OUT 0'
sudo amixer -c 0 set 'FRDDR_A SINK 2 SEL' 'OUT 1'
sudo amixer -c 0 set 'FRDDR_A SINK 3 SEL' 'OUT 2'
sudo amixer -c 0 set 'ACODEC' '85%' # not needed for the C4
sudo alsactl store

 

ANALOG

sudo amixer -c 0 set 'TOACODEC OUT EN' 'on'
sudo amixer -c 0 set 'TOACODEC SRC' 'I2S B'
sudo amixer -c 0 set 'TDMOUT_B SRC SEL' 'IN 0'
sudo amixer -c 0 set 'FRDDR_A SRC 2 EN' 'on'
sudo amixer -c 0 set 'FRDDR_A SINK 1 SEL' 'OUT 0'
sudo amixer -c 0 set 'FRDDR_A SINK 2 SEL' 'OUT 1'
sudo amixer -c 0 set 'FRDDR_A SINK 3 SEL' 'OUT 2'
sudo amixer -c 0 set 'ACODEC' '85%'
sudo alsactl store

 

Hi thank you all now the audio works!

Hi, I am here in 2026 with the Amrbian 26.2.1, I've tried the proposed fix from @c0rnelius but it's not working on my OS version. If anyone has any updated solution that'd be amazing. Thank you
