Laptop won't suspend/sleep while Wesnoth is running

[karger]

When I'm running Wesnoth on my Windows 10 Thinkpad Laptop, closing the lid doesn't put the laptop to sleep----it continues to drain battery at full operational rate. Running powercfg /requests produces the following output:

SYSTEM:
[DRIVER] Realtek High Definition Audio (HDAUDIO\FUNC_01&VEN_10EC&DEV_0293&SUBSYS_17AA2233&REV_1000\4&1253530c&0&0001)
An audio stream is currently in use.

(This only shows when Wesnoth is running.) Which suggests Wesnoth is demanding to play its sound effects and refusing to suspend. Is there a way to overcome this behavior?

Wesnoth 1.13.4 also prevents my computer from going to sleep as well, running Linux Mint.

Could this be because SDL disables screen savers? Could you try the instructions here to re-enable it throught the environment variable? https://wiki.libsdl.org/FAQUsingSDL#Why ... default.3F
If it works, we'll have to consider whether we want wesnoth to disable screensaver or not.

Thanks

I think it makes sense to disable auto suspend (that is susepnd after x miutes of inctiveness) while playing a mp game, since susepdnding the pc will automatically break the connection afaik. I do however agree that wesnoth should not disable suspending when playing in sp mode or beeing on titltescreen.

This does not seem to be the cause. I set SDL_VIDEO_ALLOW_SCREENSAVER=1 in my ~/.bashrc, logged out/in, and Wesnoth still prevents going to sleep both from within an SP scenario and when on the title screen.

So, I did another experiment with this on Mint 18.

Power settings are set to suspend after 5 minutes:

All of Wesnoth's sounds are disabled:

There is nothing doing anything with sound:

I walked away for 7 minutes, came back, the computer had not suspended.

I then closed Wesnoth, walked away for another 5 minutes, came back, and the computer had suspended.
