What results do you get if you boot your system with the USB speakers disconnected and the connect them once the system is fully booted?
I was listening to some audio when the sound stopped;  AudioEngine had disappeared from the list of output devices.  A log extract is attached  (Audio-Crash.txt).  

There may be a problem with the cable.  The speakers are attached to the computer with a USB extender cable, which may not give as good a connection as is needed.  So I moved things around and connected the speakers without the extender; we'll see if things get better.  A log extract is attached (Audio-Restore-ShortCable.txt).

Oh, I never did have much luck with USB extender cables.  FWIW, I don't use USB devices all that much.  Other than
dongles I only have an HDMI capture device hooked to USB.

With speakers, I use Bluetooth.  I find them more versatile.
Everything is working now.  A new USB cable long enough to reach from the speakers to the computer without an extension has made USB reliable.  And a new Bluetooth dongle from tp-link has made Bluetooth reliable.  And there have been some upgrades to pipewire, which may have affected things. The sound using USB seems slightly superior to that using Bluetooth.
