Ubuntu 17.10 working HDMI sound

Patrick Lamprecht

Hello all

I just found a way to get the hdmi sound to work in the newest Ubuntu to work after a lot of research.
I ran across a website where someone has described the same problem, just wanted to share it with this forum, cause a lot of people might search here first, like me ^^

Commands used:
sudo usermod -aG audio <username>

test if sound is working:
aplay -Dplughw:0,2 /usr/share/sounds/alsa/Front_Left.wav

if this worked for you, make it permanent:
sudo nano /etc/pulse/default.pa (if this file is missing install pulseaudio)

add:
load-module module-alsa-sink device=plughw:0,2

and comment out the whole block where it says: "Automatically load driver modules dependin on the hardware available"
save , restart and now your hdmi sound should work
