Hello Kevin,
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.
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
