No sound from my RPi 3 B.

  • Thanks in advance. I’ve been searching the forum and have not found an solution for this. Currently I am running a Raspberry Pi 3 B. I have MM loaded and some modules loaded. I have a HDMI to DVI cable attached going to my monitor. Any help is appreciated.


  • @BillW dvi does not carry sound so you would need a separate cable

    My main computer has dvi, monitor is HDMI. Uses sep cable to monitor

  • I should have included in my first post, but I did attach a separate cable for sound to speakers, but that didn’t work so I tried earphones to make sure. Thanks for confirming that for me. Any other suggestions?

  • @BillW did the earphones work?

  • @sdetweil do system sounds work?

  • I’ll follow the link and check it out, then I’ll let you know what I did. Thanks for the guidance.

  • Ok, tried all three but no luck, not sure what to do next. Here’s a copy of my config file if that may help

    For more options and information see

    Some settings may impact device functionality. See link above for details

    uncomment if you get no picture on HDMI for a default “safe” mode


    uncomment this if your display has a black border of unused pixels visible

    and your display can output without overscan


    uncomment the following to adjust overscan. Use positive numbers if console

    goes off screen, and negative if there is too much border


    uncomment to force a console size. By default it will be display’s size minus



    uncomment if hdmi display is not detected and composite is being output


    uncomment to force a specific HDMI mode (this will force VGA)


    uncomment to force a HDMI mode rather than DVI. This can make audio work in

    DMT (computer monitor) modes


    uncomment to increase signal to HDMI, if you have interference, blanking, or

    no display


    uncomment for composite PAL


    #uncomment to overclock the arm. 700 MHz is the default.

    Uncomment some or all of these to enable the optional hardware interfaces


    Uncomment this to enable the lirc-rpi module


    Additional overlays and parameters are documented /boot/overlays/README

    Enable audio (loads snd_bcm2835)
