System sounds volume keeps resetting to 100%

I'd like my system sounds slider to stay at 10% of the overall volume. All other volume settings seem to stick. Windows rememebers my overall / winamp / browser etc. volume just fine. Only the system sounds revert to EAR-SPLITTINGLY LOUD at seemingly random times. Sometimes after a restart (but not every time), sometimes in the middle of a Windows session. Is this a known Win10 bug?

I've turned off system sounds for this very reason.

Same thing happening here, so it's yet another new os quirk. :/

Reported it in the Windows Feedback app.
