On my Workstation install,

today after powering my computer on,

( I do not think there was an update for the past 48 hours ), my computer

seemed sluggish, especially Firefox.

In the Gnome panel at the top right,

and to the right of

the internet connection symbol,

was a white rectangle with

a tiny triangular warning sign.     There was no indication as

to what this is, but clicking on it pulled down a menu, and

the symbol was also on that menu, where I think volume normally

is ( above microphone ).     Volume was defaulted to zero, and adjusting it did not

matter.     Anyways, I have lost system sound, and have tried

various things, but nothing so far has worked.

I do not recall updating anything since I last used my computer

yesterday.

The only thing I did new, was I let the computer power-off automatically,

after 60 seconds, instead of clicking "power-off."

I have rebooted and used my computer, since I posted a question

about "database disk image is malformed" a few days ago.

I did an internet speed test, and that looked fine.

htop looks okay.
