Sound over HDMI won't work

[wowbagger]

Hello, I'm writing because I'm gettin my a** kicked by this. I'm running the latest Retropie in a Raspberry Pi 3.

Guys, I tried everything.

My config.txt has all the usual suspects set:

hdmi_drive=2
hdmi_force_hotplug=1
hdmi_force_edid_audio=1

I'm not advanced on Linux, so I simply don't know what else I can change to fix this. Is there a kind soul able to help?

after an hour of research I fixed mine

Try running this first

amixer cset numid=3 2 (there is a space between 3 and 2)

if that doesn't work try this before

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install alsa-utils
sudo modprobe snd_bcm2835

good luck

@jimkazama It's solved. I'm embarassed to admit that I dumbly forgot to uncomment somethings in the config.txt.

Thanks for the tip, nonetheless.
