Ask Ubuntu Asked on November 6, 2021
Everytime I shut my computer down or reboot it there is a very loud pop/crack from the speakers. It sounds dangerous, like they are going to blow up. Is there a way to automatically mute the volume on shutdown?
The computer often seems to make beep noises or other sounds at various times, whether we want them or not. They come from various sources, and as such, you may be able to configure if or when they occur.
Blacklisting the pcspkr module will prevent udev from loading it at boot:
# echo "blacklist pcspkr" | tee /etc/modprobe.d/nobeep.conf

I have Kubuntu 19.10 and had this loud popping problem.
[note: you need to be root for this].
Open file in console using: sudo nano /etc/modprobe.d/alsa-base.conf [or, use Dolphin, open with Kate.]
Add the following line at the bottom of the page:
options snd-hda-intel power_save=0 power_save_controller=N
save and reboot.

Open terminal and do:
Code: gksudo gedit /usr/lib/pm-utils/power.d/intel-audio-powersave Find this line:
INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
and comment it out by putting a "#" in front of it like this:
# INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
Just below this line you make a new line, like this:
INTEL_AUDIO_POWERSAVE=false
So now you will have:
# INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
INTEL_AUDIO_POWERSAVE=false
Save the file (File > Save) and exit.
Reboot the computer.
The popping sound will be gone.
NOTE: If you for some reason need to undo the setting, just open the file again and remove the "#" from:
INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
and delete this line:
INTEL_AUDIO_POWERSAVE=false
Save the file.
Reboot.

That's a known bug: https://bugs.launchpad.net/ubuntu/+bug/373452 Do you have an HP laptop?
Answered by jonbonjovi on November 6, 2021
The popping is not a result of your computer not being muted; it's probably a result of capacitor discharge being sent to your speakers.
From what you've said, it sounds like you have a set of external speakers? If this is the case, turn them off before booting down; this will prevent any discharge from being amplified, and therefore being heard.
