No sound or sound not working after newly installation

Hello good night.
I want to ask for some suggestions to fix the sound that is not there or maybe even not working on my laptop. I’ve followed some suggestions and tutorials from various people and sources but it’s still not working. maybe i missed something? I beg you from this post I find answers to the problems that occur. thank you.

Welcome to Manjaro forum

this is the output, is there a mistake?

You have 2 sound devices detected.
Being lazy why research them, you tell us which one you want sound out of please.

if you install pavucontrol and execute
pavucontrol

and go the far right ConfigurationTAB your options are:
disable HDMI often its the top one
to laptop speakers, often the bottom one, choose Analog stereo duplux

or
for top one, choose some kind of digital surround sound out and
turn off analog sound

the go to Output Devices TAB
if the volume slider is faint you need to unmute by clicking the mute/unmute button at top, third from the right.

You can also adjust volumes with media players like vlc

good luck

thnks u i will try this :laughing:

Check if package pulseaudio-alsa is installed

Manjaro i3 can have a problem when installing PulseAudio that additional package pulseaudio-alsa is not installed (a recommended optional dependency)
The package creates the ALSA configuration for PulseAudio to be default instead of a specific hardware device

If the package is installed and audio is not working, please post more information

this is the output when i run it amixer -c1

but when I run pacmd dump the output that comes out is

Neither PulseAudio daemon is running, nor is it running as a session daemon.
