Is there anything I need to look out for when searching for a pair of US
$20 USB connected computer speakers. This is for background audio, not
recording nor monitoring. I'm mostly interested to know how careful I need
to be to make sure USB speakers work on Linux.
Thanks folks!
Be well...

Not very… I use some USB speakers on my workstation at work, a cheap
Logitech set.
Bought for testing a SCADA driver that I had written to play a recording
on loop when a particular SCADA tag was toggled. (The application here
was audible alarms for a coal train weighbridge system. PortAudio +
libsndfile, stuffed into a MacroView "sorted image" driver --
dynamically linked of course!)
The only thing I note is there's a mixer quirk: they don't report the
supported range properly and so `alsamixer` basically has 5 levels: 0 is
off, 1 is quiet but still audible, 2 is a bit louder, 3 is basically
normal volume. Full volume is 4, and anything above that is
indistinguishable from 4.
Other than that, they seem to work just fine for the times I use them.
Definitely not audiophile grade, but good enough for casual use.

Hello Kevin,
Is there anything I need to look out for when

Almost all USB audio interfaces are class compliant these days, which
means they should work on most operating systems with the standard
drivers. And if the speakers don't work you could return them. If you
don't feel like doing so you could check if the manufacturer has a
manual online, if so it should definitely mention somewhere if the
device is class compliant or that it needs specific drivers.
Best,
Jeremy

Regardless of operating system, one disadvantage of USB speakers
compared to conventional speakers (ones with analog audio inputs, e.g.
via a 3.5mm jack from a soundcard) is that the former might be
vulnerable to BadUSB whereas the latter would not be:
