Hey Borgmac!
Of course we’d all love to hear a recorded sample of that sizzle…

Hi FBz, good to exchange with you again.
OK, I knew someone would point that out. Knowing that I am French speaking, I was not sure of the wording.
After checking more thoroughly, I found this article, very good examples of different sounds defects.

I would say that my sound is something like sizzling (but with a thick bacon ;D), Hissing and Static.
Like when you connect a speaker live and you do not insert the plug quick enough.

Perhaps your QS is just more sensitive lately?

This has actually been for months, I was just too lazy to look seriously at it :-[

The very first step here is to startup OS9 - Shift key held down - for "Extensions OFF"

How could I have missed that. 35 years working on Mac and I forgot the most obvious check and the Extensions Manager >:(
Too much working on Mac OS X...
Thanks to remind me of this one.

Seems intermittent?
So the software decides to sometimes sizzle, sometimes not?
Only once in OS 9.2.1… and almost every time with Z1 9.2.2.
Pull the adapter and SSD and transfer them both intact to another Quicksilver to see if the sizzle also transfers.
(You still have more than one QS there?)
No sizzle? Then swap the CPU also, to the new machine in an attempt to replicate the sizzle.

Yeah, Yeah, I know what you mean, may be after all a hardware problem. ::)

OR, you might even try to reload or update Z1 9.2.1 (international version) to 9.2.2?

That was my next step actually, but I am going first to try the Extensions Manager (see answer to GaryN post)

May be a hardware issue actually...
How could I check that?
Borgmac:
And here is the sound.

Any idea what could cause it?
Actually this time it did start while loading extensions and stop at the desktop display.
As usual , no sound anymore after that.
So the test of the extensions is next.
