[Latest] Armbian Build HDMI Audio support Fix

[just_facking_about]

Fairly sure the current build either includes an incorrect or no ucm config for HDMI Audio support; I've seen other builds eg rock itx have this issue but I believe this may be a potential issue for the q6a build if anyone experiences there is a solution -

 

1. Install alsa-ucm-conf

sudo apt install -y alsa-ucm-conf

 

2. Download configs

 cd /tmp
curl -sL "https://github.com/alsa-project/alsa-ucm-conf/archive/refs/heads/master.tar.gz" | tar xz

 

3. Copy QCS6490 configs
 

sudo cp -r alsa-ucm-conf-master/ucm2/Qualcomm/qcs6490 /usr/share/alsa/ucm2/Qualcomm/
sudo cp -r alsa-ucm-conf-master/ucm2/conf.d/qcs6490 /usr/share/alsa/ucm2/conf.d/

4. Copy library & codec files

sudo cp -r alsa-ucm-conf-master/ucm2/lib /usr/share/alsa/ucm2/
sudo cp -r alsa-ucm-conf-master/ucm2/codecs /usr/share/alsa/ucm2

5. Restart PulseAudio

systemctl --user restart pulseaudio

 

6. Verify HDMI audio is detected

If this did not work i probably just made your issue harder to fix; However if this did work congrats enjoy not having a mute computer.
