The first breakage was with the introduction of newmidi IIRC. The mixer
worked, but any dsp related functions were broken.

See: sys/dev/sound/isa/es1888.c rev 1.3

In recent kernel even the mixer is dead and the soundcard is left in a
state where all volumes are zeroed, preventing audio CD playing as well.

See: sys/dev/sound/isa/es1888.c rev 1.4

Relevant kernel config options:

options         PNPBIOS
controller      isa0
controller      eisa0
controller      pci0
controller      pnp0
device          pcm0

I have to re-enable sbc0 to see if any changes therein apply to ESS as
well. Should I have sbc0 in the first place?
