Sounds keep playing after laptop is suspended  

explain suspend what do you mean by this exactly?

To set the context for your situation, please show us your available power states by posting the response to this command

Code:

PowerCfg -a

You can check what happens at the time you tell it to "suspend" by looking in Event viewer. Here's an Event viewer, Custom view definition for sleep-related power transitions together with import instructions.

Sorry, I meant to say sleep instead of suspend, as that's the equivalent word in my language. Thank you for the guide, but there are no events with Source "Power-Troubleshouter" or EventID "1" as depicted in the image of your tutorial ("Resume from S3 Sleep, Details tab") after the laptop goes into sleep. And here's the output of the powercfg -a command. I can only give you an approximate translation to English, as you might know, you cannot change display language in Home Single Language edition, though I believe you'll be able to interpret it:

Code:

Microsoft Windows [version 10.0.19045.2364]
(c) Microsoft Corporation. All rights reserved.

C:\Windows\system32>powercfg -a
The following sleep states are available on this system:
     Standby (Idle S0 with Low Power Consumption) Connected via Network

The following sleep states are not available on this system:
     Standby mode (S1)
         System firmware does not support this wait state.
         This sleep mode is disabled when the low power idle state of S0 is not supported.

     Standby mode (S2)
         System firmware does not support this wait state.
         This sleep mode is disabled when the low power idle state of S0 is not supported.

     Standby mode (S3)
         This sleep mode is disabled when the low power idle state of S0 is not supported.

     Hibernate
         Hibernation has not been enabled.

     Hybrid Sleep
         Standby mode (S3) is not available.
         Hibernation is not available.

You do not have S3 Sleep. You have S0 Modern standby [aka S0 Low power idle].

The Custom view does not just monitor what is in the diagrams. The diagrams are, as explained, there to point out very specific points about the records.

You enter S0 when your display turns off. You can check that against the Custom view.
S0 is not sleep.
S0 progressively inhibits tasks running on the computer.
If your audio keeps playing for a period despite the onset of S0 then that might be correct operation for all I remember [I disabled S0 quite some time ago].

OK, I gave a quick read about ACPI, and S0ix sleep state is Modern Standby (or InstantGo), but shouldn't traditional S3 power state (Sleep, Standby or Suspend to RAM) be available in this laptop as well? I think this is what Linus Sebastian has criticised in a recent video due to high battery drain caused by this specification, which is something I've noticed myself.

Anyway, I guess this behaviour is (unfortunately) normal then, thank you very much Denis for the assistance.

Well, you could do as I did and disable S0.
Many people have found that disabling S0 automatically enables S3 Sleep so you can have a computer that behaves as you expected it to. [Not me though, I now only have on, hibernate & off but it's better than putting up with S0 as far as I am concerned]
The procedure is quick, simple & easily reversible so you can try it out to see if you like it. It's a simple Registry change.

I did it but no change, S3 is still unavailable, though I believe I can get a bit longer battery life. Sounds keep playing but stops after a while, but it seems to be completely random, sometimes playback will stop immediately, sometimes it will take way longer. This Modern Standby feature is one of the worst things Microsoft in its infinite "wisdow" has ever implement in Windows, as they "fixed" what wasn't broken. Anyway, I guess there's nothing I can do, thank you very much for the help Denis.
