system sound + Libreoffice

Good evening
I noted a very strange behavior.
Although I have set Windows (10) system sounds to "no sound",
in more or less frequent intervals the systems starts beeping (e.g., when switching to Caps Lock).

This happens ***ONLY*** when I am using Libreoffice.
It used to go away, when I reset the "no sound".
By now, this does not work any longer. The computer annoyingly keeps "beeping me crazy".

Is there a trick to stop that behavior???

Thank you
Thomas

Do a memory check immediately.

See https://lifehacker.com/5531900/use-an-ubuntu-live-cd-to-test-your-pcs-memory

Also try Writer with the live boot CD if it occurs under linux.

Hope this helps.

Last time I heard of this type of problem was in the early Windows days [i.e. Windows 95 era?].  ASCII has a non-printable character that actually causes the beep noise with the motherboard hardware.

The question is whether the "no sound" is for the sound card, the MoB's "beeper", or both.  Even if the "no sound" stops the hardware beeping, I would bet that LibreOffice might flip the "flag" used by the "no sound" option on the motherboard and not the sound card.

Those early days of PCs. PC-ATs, PC-XT, etc. did not have a sound card on the MoB.  You had to buy one that work with your PC Bus slot.  So most developers used the "beeper" character instead of using an optional sound card.

SO, there may be something withing the oldest surviving code that may mess with the "flag" settings dealing with sound.  I remember something about the early days with StarOffice[?] running on DOS

Hopefully I have "solved" the problem

Since the computer did not act so before, I have no idea how this came to pass, but there is a KEYBOARD setting
designed to make sounds when toggling keys.
I turned that OFF ... and now the computer finally keeps quiet - VERY helpful when working at 2 am (now!)
