I guess this is a known "problem", the strange hardware implementation
where exposing the dummy HD-audio bus with non-existing codec. So
this can be ignored as well (maybe we can blacklist the PCI ID for
ignoring more properly).
The real issue is:

So it's likely a USB audio firmware that doesn't behave correctly as
advertised, and we'd need a workaround.
Could you give lsusb -v output for this device?
