Beeping sound when cursor pressed on TLazVirtualStringTree (The plot thickens..)

I'm using, for the first time, a TLazVirtualTreeView in my app. I've also opened up the "virtualtreeview/vst_minimal" example app to get to grips with the component. In both the example and in my app, a cursor down or a cursor up produces a strange beep on every key press.
Can anyone tell me why it does this, and, more importantly, how to stop it? ;)
Thaddy:
To stop it, turn down the volume.
It is not caused by fpc code, but it is an OS "feature" and such things should really not be "fixed".I supose you are on Windows? You give us very little information.
TRon:
The funny thing for me is that I am running a particular linux distro on several different machines. Only one of them seem to have the DE system sounds enabled by default while on the other machines it does not. Might perhaps depend on what packages are installed (different hardware) but I found it interesting inconsistent behaviour nonetheless (I probably should ask the maintainers about that).
Martin_fr:
Well, at least your OS, and Desktop manager....
I don't get sound from the virtual tree view.
If you use Lazarus 3.x open the watches window, add a few watches and go up/down with the keys => I don't get any sound (not on Windows, not on Fedora 37 (Gnome))

Sorry, I forgot to post my system specs. Please see the original (amended) post,
but to save your, no doubt, valuable time, I'll mention it again...

As for your answer, did you mean that seriously?
I take it from the tone of your comment about the OS that you are not on Windows, either. I despise Windows as a product but I try to restrain myself from talking down to its users!
My form currently has a TListView which does not exhibit this "beeping" while the TLazVirtualTreeView component beeps like crazy in both my app and the "vst_minimal" example app. If it is an OS "feature" it must be a remarkably selective feature, or maybe there is something that only manifests itself in macOS, presumably due to insufficient testing.
