I have an old Dell Latitude E5430 laptop running DietPi Native PC (x86_64). *DietPi is a fork of Debian 11 Bullseye.

Summary

Today, I installed beep and ran it. It put me back into bash a second later. There was no sound. Strangely though, using a terminal music player called "cmus", sound actually works and it play with no problem.

What did I try

  • I installed the latest Linux Intel sound card drivers
  • I installed ALSA
  • I set the volume to maximum in ALSA Mixer

Additional info

Inside of my /etc/asound.conf:

pcm.!default {
        type plug
        slave.pcm {
                type hw
                card 0
                device 0
        }
}

ctl.!default {
        type hw
        card 0
}

I confirmed that the speaker is connected.

This command is used to control speaker, not sound card. So if on your computer you have no connected speaker you can expect to hear nothing.

To quoting one commend:

small piezoelectric buzzer/speaker usually connected through two wires directly to the motherboard and installed internally, not external speakers you plug in

  • Sorry, I forgot to add that. Yes my speaker is connected and is functional as said in the original question. – David Dec 27 '22 at 13:41

    Its not any external speaker that matters here, beep beeps the small piezoelectric buzzer/speaker usually connected through two wires directly to the motherboard and installed internally, not external speakers you plug in. – tkausl Dec 27 '22 at 13:55
  • Did you see more than about 10 sound channels in the alsamixer? If not, try pressing F6 and selecting a specific soundcard instead of "default" (which could be the simplified mixer provided by Pulseaudio). When you get the actual hardware mixer of the sound card/chip, it should have a large number of channels with independent volume and/or mute settings. One of those might be labelled something like "Beep". It is usually muted and at volume 0 by default. Unmute that and turn its volume up, then try the beep command again. – telcoM Dec 27 '22 at 14:31
  • Also, you may have to add yourself to the input group to be able to use the beep command, unless you are root (sudo usermod -a -G input $(whoami)) – telcoM Dec 27 '22 at 14:35

    Unfortunately, some laptops simply don't wire the beeper/buzzer output of the system chipset into the sound chip and don't provide a classic (pre-soundcard) physical PC buzzer/beeper at all. So it is possible you are simply out of luck with your current hardware. Then you'll have to use something like aplay beep.wav instead. – telcoM Dec 27 '22 at 15:01
