I have a mysterious driverless device called "iAP Interface" now, any suggestions?
There's a guy posting youtube videos about this DAC, and he has provided a solution to the iAP Interface problem: you need to install a separate driver for it. Worked for me. The download is in the comments section, all in Spanish so you'll need to translate. Or below is the link on google drive for the driver he provided. After installing, the "iAP Interface" disappears from device manager and "SONATA-HD Device Control" appears in USB controllers.
