Windows 10: Laptop suddenly not making beep sound when plugged in/unplugged

My issue is exactly as described. I am on an Acer swift sf314-511, running Windows 10 Home. Since I got this laptop, whenever it was plugged in or unplugged, it made a beep noise to notify me of this. This extremely useful sound has suddenly stopped occurring. a USB being removed or inserted still makes that associated sound, but not the charger all of a sudden. I cannot seem to figure out why. any help would be extremely appreciated.

Disable beep sound when plugging/unplugging laptop charger

My laptop makes an annoying beep sound whenever I plug or unplug the charger.

Windows 8.1/Windows 10:

Disable the System Speaker device:

1. Open "Device Manager".
   
2. Scroll down to "System Devices".
   
3. Click on "+"
   
4. Right click on "System Speaker".
   
5. Select "Disable"
   
6. Restart your computer.
   

Beep should be permanently disabled.

Windows 7:

Disable the Beep device:

Disable beep sound when plugging/unplugging laptop charger

My issue is the same as in this question, but none of the answers there helped solving my problem, so I'm hoping to get alternative suggestions here.

My laptop (Acer Aspire S5-391 with Windows 10 Home 64 bit) makes an annoying beep sound whenever I plug or unplug the charger, which I'd like to disable.

The following solutions I found in the linked question and in other places did not work for me:

• My BIOS doesn't provide a setting for power control beep.
  
• My playback device settings don't show the "PC speaker" bar, so I can't mute it.
  
• I don't have the Realtek audio driver, so I can't uninstall it. When I automatically search for a new audio driver via device manager, the search won't terminate. When I donwload the driver from the Acer Support site, I am only offered the Realtek driver (which seems to be a possible cause of the problem according to some sites) which anyway fails to install.
  
• My device manager doesn't show Non-Plug and Play Drivers, even after enabling "Show hidden devices", and therefore I can't see and disable the "Beep" device. According to LPChip's comment on DavidPostill's answer, in Windows 10 the "Beep" entry is labelled as "System devices" > "System speakers", so see the next bullet point.
  
• Edit after DavidPostill's updated answer My device manager doesn't show "system speakers" under "system devices" (which seems to be the equivalent to the above for Windows 10), so I can't disable them. Possibly my laptop doesn't have separate system speakers so the beep comes from the normal built-in speakers, in which case I probably won't be able to manipulate something in the device manager without also affecting all other sounds.
  
• "Default beep" in the system sounds I already have disabled (so this apparently isn't the correct option anyway).
  

Gloabally disabling sounds mutes the beep, but is not a desired workaround for me - I only want to get rid of the charger beep, but still want to hear other default system sounds (or at least some, I alreay configured these in the control panel, but didn't find an option specifically for the charger beep; I think this is a matter of driver or BIOS settings rather than default Windows settings, but am not completely sure).

I have an Acer Aspire 3 too, though mine has now upgraded to Windows 11.

Many would give their eye teeth to be able to turn off that beep. *Biggrin

This seems to be a uniquely Acer thing. All Acer laptops seem to make that beep when the power is connected/disconnected, and there is no obvious setting in Windows or the bios to turn this on or off. Following the trail of those trying to turn it off suggests this is where you need to look:

In your case of course you need to make sure the Realtek HD Audio Manager is fully enabled rather than muted.

I've tried it on my Acer Aspire and can confirm that muting the Realtek HD Audio Manager (or Universal Service as it appears in W11) does indeed turn of that beep, quite independently of all other system sounds or audio output. Settings has a quite different layout in Windows 11, but still has all the same settings as Windows 10. This is what I see in W11's Settings.
