Looks like you have to install an Asio driver. If there isn’t dedicated one for your soundcard you can use Asio4All or the driver that comes with FLStudio. According to @mburk and @readme the latter seems to be more reliable.
I can also confirm I have had good experiences with the ASIO driver of FL Studio.
It’s a bit odd that you have to install this huge software just to get the FL ASIO driver. But you can deinstall FL Studio afterwards and just keep the driver.
