This conclusion is because the card works in another system which reports that it is using that driver for it. The reason for that appears to be the fact that for some reason, snd-usb-audio doesn't exist in the system, even though I can see that it has been enabled as a module in kernel configuration. 11 minutes to read 6 contributors Feedback In this article Architecture Related USB specifications Audio formats Feature descriptions Descriptors Class requests and interrupt data messages Additional Information for OEM and IHVs IHV USB Audio 2.
