The SSID in the above is the codec SSID.  That can be different from
PCI SSID although they are identical in many cases.

Realtek codecs suppose that the codec SSID is set to represent the
hardware implementation status so that the driver can initialize
based on it.  The message above shows that your machine doesn't
provide such SSID (as many vendors don't follow that policy,
obviously).
