If sound card doesn't need specific codec device, just dummy codec is enough, then we can link the dummy component directly.
This is a big red flag - what circumstances are these? If it's a simple CODEC with no control then the general approach is to provide a driver which announces the capabilities of the CODEC and can be bound to as normal, the dummy component should never actively be used.
For the DMIC, SPDIF, HDMI ARC device or other similar device that there is no codec connected, then dummy codec is just used for registering the sound card.
