No sound!!!!

What a relief! I was starting to panic. Sound had ceased to work in my computer. I've really needed a new computer for a while, but really can't afford one, and dreaded having to find the money (that is, borrow it) to buy one.

I keep several operating systems on my computer, so I booted into another one, to check. Gratifying surprise! The sound worked. So it was not a hardware problem... thank goodness.

So back to my preferred operating system. Why isn't sound working in it? I tried everything I could think of, but was reluctant to spend hours on the net searching, so I began with asking ChatGPT-4o if it had seen anything on the net about this particular problem. It spent a little while searching the net and came back with 8 suggestions gleaned from its search.

The first suggestion I'd already tried.

The second suggestion (to check that alsamixer was not muted) solved the problem. How it had got muted I have no idea, but now everything is okay again.

Whew! My relief is overwhelming. :(

New teeth

Human trials have begun on a drug that reverses the standard tooth regrowing suppression in humans and many other species. I doubt I'll benefit from this, but I'd love to regrow my lost teeth.
