• Cannot Get Speakers Built Into My Monitor To Work


    This is the monitor I own. It has built in speakers, but I cannot get any sound out of them, regardless of which port on the motherboard I use or which setting I fiddle with in PulseAudio Volume Control. Plugging in headphones on the motherboard works fine. I use a DisplayPort cable for video and an audio cable for audio. PulseAudio Volume Control indicates there is sound being played, but I don’t hear a thing.

    I searched around the forum a fair bit so I’ll provide the outputs of some commands that may be useful.

  • I have looked at those threads and even tried a good deal of the commands depicted in them, posting their outputs in the opening post, but no luck. As I said, headphones work fine, it’s just the speakers built into the monitor that do not, despite PulseAudio Volume Control saying there is sound being played. Apart from connecting a friend’s laptop to see if the speakers work in Windows, I don’t know what to do anymore.

  • Hmm. Ok.
    Are you at least able to bring up pavucontrol and make necessary edits from there?

    EDIT: I just noticed something. Look at your output for:
    cat /etc/libao.conf it says no such file or output.

    Mine is

    cat /etc/libao.conf
    default_driver=alsa
    dev=default
    
    

    And yes, I have the same as you:

    cat /proc/asound/modules
     0 snd_hda_intel
     1 snd_hda_intel
    
    

    Can you please confirm: sudo pacman -S libao.
    No need to re-install if already installed. Just confirm.

    Or confirm with pacman -Qi libao and look for the “Provides” , “Required by” and check if validated by signature. Look also for “Install date” as this should confirm to you it was installed.

    Also, I would like you to search for the .conf file
    find / -iname "libao.conf"

    It should tell you it is found in that same directory /etc/libao.conf It probably will not because your output states that it was not found.
    There is, on the Arch Wiki, a wiki page on Pulse Audio as well as separate page for libao

    Please confirm ALL.
