The patch is apprently not enough.
We need additional codes in snd_ice1712_ak4524_write() to send signals
to ak4524 correctly.
Most likely there are gpio bits for codec selection, data and clock
lines.  Looking at the photo of the card, the DSP24 Value looks like
having fairly different usage of gpio.  If we really have no info
about this card, we need to guess from other cards how the connections
are..  Well, it's not a good dream..

Since your card was recognized as STDSP24, it means that both cards
have the same sub vendor/device id.  Thus it's difficult to guess
which chip is.  Perhaps trying to detect ak4524 at first, then one 
can recognize it as DSP24 Value or not.

They are harmless.

Do you mean whether the routing itself doesn't work, or ADC volumes
cannot be controlled?  The routing is a generic function of ice1712,
so this must work regardless of the card model.
