Initially when I installed Manjaro, sometimes the sound seems to work, sometimes it didnt, while it was fine on other distros; till I finally found out what was happening.Here's how it goes-Note
-I am using the default/standard configuration (pnmixer +alsa +pulseaudio +pavucontrol)
The problem is that it doesnt synchronize
well, I will explain what I mean with the help of screenshots.
(left click on your volume icon in the tray -> Volume Control to check what I type)
1.)When I muted my sound via the Fn+F8 key, or by left clicking on the volume icon - > mute,
the mute icon in the output devices of volume control would be greyed out both in the system tray and the pavucontrol and in notification also. - Pic No 1
2.) But when I unmute
it either with the Fn key or by clicking on the icon -> Unmute
everywhere in the notifications I see that it is unmuted, but in the volume control (pavucontrol) ,it is Still Muted!

So there you have it! Thats what I mean that its not synchronizing correctly.
This problem could also be the reason, for example, when you plug in your headphones
, and the system is showing that the sound is on, whereas In Fact It would be Off in the volume control( pavucontrol) for your headphones output
In that case try to do
is to click the greyed out mute icon in the volume control to re-anable your sound

A simple solution if it works, no uninstalling/ reinstalling, or messing with configuration files.
