I did not comment recently because the system has "magically" been OK.
I've recovered the sound and the latency has disappeared and I do not know
why?
Later I've got the possibility to update the system and still no error came.
It is fine now but I do not understand why the system came back with no
problem if I did not install or update anything.
Does anyone may have an idea about this?
I am of course thinking about a possible breach / security / hacking issue on
my system during some days, before everything comes back to normal.
Can anyone help on this?
Best.
