No monitor sound (DisplayPort)

Hi everyone. New Manjaro user here.

Just installed Manjaro XFCE to dualboot with Windows 10. Sadly I’m not getting any sound from my monitor, although it works when I plug a headset in my PC.

In the Volume Control the soundbar is moving up and down as if there is sound registered, its just not coming through the speakers.

I have downgraded to the latest LTS kernel (5.4).

Hope you can help, cheers :slight_smile:


maybe try this. Open a terminal. Type in:


type F6 and change from standard to another soundcard. Try to adjust the sound there.

Sidenote: alsa is the soundsystem and pulseaudio works on top as “layer” to control alsa more comfortable.

Thanks for you answer!

I can change in between:

  • (default)
    0 HDA NVidia
    1 HD-Audio Generic

Where especially 1 has several adjustments available. How come, I don’t think I’m able to save changes?

When I write up alsamixer after changing soundcard, it’s back at - (default).

The changes you make in alsamixer are normally saved immediately.

Think of this:

Application makes sound -> goes to alsa -> and then to pulseaudio

alsamixer can be adjusted and pulseaudio, but if alsa is set to 0 then pulseaudio wont get any sound to play.

I see. When i just run alsamixer I get a different screen than if I run sudo alsamixer.

Running sudo alsamixer makes the HD NVidia pop up as selected, where there is only S/PDIF’s showing with no adjustments possible. However, PulseAudio is not showing no matter which soundcard I change to.

Running alsamixer makes the default PulseAudio pop up where I can adjust the master item and I can switch between soundcards.

Solution to this problem turned out to be the open-source gpu driver. Installing the proprietary one and removing the open-source one made it work.
