EEPROM contents.  not for mixer.

the internal clock of the board.
note that ice1724 has a single rate for all channels.

the rate locking - allow each app to set the rate or use
the fixed rate.

> numid=4, iface=MIXER,name='Multi Track Rate Reset'

reset the rate to the default value at each time the PCM is closed.
(the default value is the last internal clock rate.)

the analog output routing for each channel.  they're enum.

peak meter.  read only.

> numid=14,iface=MIXER,name='IEC958 Playback Route'

spdif output routing (left/right).  the enum valus.

> numid=16,iface=MIXER,name='IEC958 Output Switch'

turn on/off spdif output.

> numid=17,iface=PCM,name='IEC958 Playback Default',device=1

spdif status bits.  32bit long.

> numid=18,iface=MIXER,name='IEC958 Playback Con Mask',device=1
> numid=19,iface=MIXER,name='IEC958 Playback Pro Mask',device=1

available spdif status bit mask for consumer and professional modes.

DAC = digital-analog-converter
for each analog output channel.

> numid=28,iface=MIXER,name='Master Playback Volume'

master playback volume for analog outputs.

> numid=29,iface=MIXER,name='ADC Volume'
> numid=30,iface=MIXER,name='ADC Volume',index=1

ADC = analog-digital-converter
for each analog input channel.

> numid=31,iface=MIXER,name='Capture Route'

the recording source selection.   the enum values.
