AFAIK au8820 do not has any Equalizer, only au8810 and au8830 have the
Equalizer.

Those Equalizer offsets 0x2b??? are out of the 128K MMIO of au8820.

Most of the changes related to Equalizer are seem to be WRONG.

Please ask the alsa-team to add your Diamond Sonic Impact S90 (au8820)
to the soundmatrix

http://www.alsa-project.org/alsa-doc/index.php?vendor=vendor-Diamond_Multimedia#matrix


au8820 do not support SPDIF too.

Is  IEC-60958 RCA Output equal to Coaxial SPDIF ?
Is  IEC-60958 TOSLINK Output equal to Optical SPDIF ?
Is  MIDIio both equal to MPU401 ?

Do anyone know why amixer display 10-bands EQ stereo controls as mono 
controls ( snd_mixer_selem_has_capture_channel(elem, 
SND_MIXER_SCHN_MONO) = 1 ) ?
