[NotMyWay]

I just realised a way to fix this problem... somewhat unconventional but works anyway.

Go to control panel and click "sounds, speech, and audio devices". under the "sounds" tab, select "exclaimation". (located under the "program events", u may need to scroll down). next, change the sound to "(none)". U may want to save the scheme as a custom scheme, so that u can change the schemes easily when needed.
