Yes, quoting Clemens Ladisch:

These chips cannot be connected directly to a PCI (or similar) bus; they
expect audio data in a simple serial format and require some controller
chip that does DMA from/to the computer's memory.

The ALSA driver, if it existed, would be for this controller chip.

Do you have some particular sound card in mind?

Those are chips that have a PCI or ISA interface.
