Actually the real problem/cause is not an app.
It is a web site..
But your suggestion to look at recent app installations did help in me thinking of some theories
ie chrome.
It is a chat website..
That is why it was harder to find out the cause..since I got lots of tabs open
and it is nothing special about that website..
If it was a spam ad, I would notice it immediately
since I got popup blockers and ublock addon
It is definitely one of the weirdest unique windows problem I have encountered in a long time..
I tried google this problem (to see if google can solve this) prior to asking help here and there was no solutions..
Any thanks for trying to help me solve this problem..
The solution should not be too hard to find.
I will update this thread if I fully solve this problem and no more sound occurs from now on.
