Since an updage to RaspiOS on my Pi4 a couple days ago it's become hard to watch YouTube videos; Chrome won't play at all, and FireFox is without audio.
The odd thing is that the trouble didn't emerge immediately: It took a day or so for Chrome to quit working, FireFox played the first video normally and lost sound after that.
I just check updates, the system reports "up to date". I'm using analog output, if that matters.
Thanks for reading and any ideas.
