I'm using Raspbian Stretch Desktop for my Raspberry Pi 3B.
I'm using a VGA screen with an HDMI to VGA adapter, so I want the jack to work as my main audio output. If I unplug the HDMI and reboot, the speakers work as intended, but whenever I plug it, they stop working because the audio output is sent through the HDMI.
What I want is to force the audio output to be through the jack.
Since doing it from sudo raspi-config menu didn't work, I tried what lots of people in lots of forums say, and I used this command:
amixer -c 0 cset numid=3 1
But it doesn't work for me (I tried with every posible number combination, just in case). I also uninstalled pulseaudio because someone said it may be a workaround to the problem, but it didn't work either.
Notice: I rebooted the RPi a lot of times while trying this.
Does anyone have any idea of what the problem is and how can I solve it?

SOLUTION:
The problem was with omxplayer. It seems to ignore the configuration and use its own. Fixed!
