Re: ice1724 controls meaning

[Andrew Gaydenko <a@etver.com>]

Takashi,

Thanks! With your help (and after playing with alsamixer, (patched) qamix and pencil)
I have recognized almost all I have wanted. Nevertheless, one control isn't clear for
me (the issue isn't a stopper anyway). I mean 'Capture Route' enum items mnemonics. For
example:

- for "CD In 1" card input both the control values must be 'CD Left',
- for "Line In" input both control values must be 'Aux Left' (or 'Aux Right'? - don't 
  remember now, but it isn't important). 

You see, both control must have the _same values_ for normal _stereo_ capturing. I can
suggest three reasons of such inconsistency:

- my brain,
- the way concrete card manufacture has designed the card (Terratec Aureon 7.1 Space),
- the driver.

Which case to choose?

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.
