Hi,

s'cuse me if this has been asked before, but has anyone had any
experience with a Behringer UMC1820 soundcard under linux? If yes, how
does one change properties of the card such as sample rate, etc?

Looks like the cheapest™ USB class compliant card with more than 8 I/O
on the market right now....

All class compliant USB devices work in the same way, since they are controlled by the same device driver (with minor variations for "quirks").

The sample rate is controlled by the application using the device.
