I haven’t found anywhere to disable game mode....
hmmm..cog wheel / to turn off apps/ xbox/ and perhaps radios? and anything that can cause issues, or takes up resources...and do not let apps use, what you feel is a possible cause for interruption of devices.
I would check the = "services." for the xbox crap...and turn it to disable, and anything to do with it...can't remember right now, but go through the list, and double check em out, on the web for what those other services do, liken spying or telemetry sending , or collecting..auto updates, and any programs with auto updates, to set to disabled or manual...to stop the interruptions, or checking for updates while working especially MS Windows, because it holds it in memory, or ties to the notifications a bell or ticket to inform, untill you address it.
might want to turn off notifications also while one goes hunting for any changes MS Windows has done.
Might have to uninstall your audio driver and reinstall it...
And for the odd sounds?...check to make sure "windows sounds" have not been re-enabled, make sure all usb device hubs are not powered down by windows in device manager...uncheck the boxes that say.."Let windows turn off power for this device"
check for latest updates for all the system drivers , bios, and firmware.
Seeing as the telemetry of MS and third party people must use a connection to the world wide web, of spiders and snakes selling your info to others...and not giving anyone a dime.
Bing may use internet explorer to do the dirty deed...windows sounds, and drivers for sound may be affected by the deeds doing it while it has a chance to do whatever it is doing...browsers are tied to audio devices, and notifications may call system sounds...perhaps?...look into these things also:

SOMETHING MIGHT BE SENDING MIDI CHANGES?..OR NOTE?...MIGHT BE MS GM GS RELATED?
hope it helps.
Cheers.
