Hm, snd-opl3sa2 _should_ be the right driver. sb8 may work because your device has a compatibility with old-good SB8. But, the functionality supported by this driver is far less, of course. I can't give a better advice here since I don't have information requested (the sys entries for NM2210). Also, the bug might be related rather with pnp layer...
