So I recently bought a USB PCI card for my computer to resolve an issue with audio popping/crackle. (I use it for my headphones). It works for resolving the issue, however whenever I run an application that uses audio, audiodg.exe uses roughly 10-15% of my CPU. The card is a Fresco Logic FL1009. I'm thinking that it may be a driver issue. The earliest driver I can find for it is from 2013 and the driver windows gives to it automatically (as a standard driver) is more recent, but it does not work. Plugging my headphones into other USBs on my computer doesn't cause audodg.exe to go any higher than 1% CPU usage, although I will get audio popping. I've done the basic steps and disabled audio enhancements from playback devices and it does not fix the issue.
