MED3931 card did not work (failed with "OPTI chip not found") because snd-opti9xx gets mc_indir_index from pnp by adding 2 to the pnp-reported port. It probably works for some cards but not for this one. Datasheet says that the port is always at 0xe?e so just force the lowest nibble to be 0xe.
Also this card powers up with (ugly) 3D sound enabled. As there's no mixer control for this, just disable it.

Applied. Thanks.
