My understanding was that ice1712 data format is always 24-bit 'loose-packed' 
into 32-bits (ie with 0's added), the ice1724 is probably the same?  That is 
what the Terratec DMX6fire handbook also says.  The chipset is 24-bit/96Khz 
capable.  Hardware mixing of 10 inputs and 10 outputs is provided.  In the 
notes, it is probably worth mentioning Envy24control, a mixing/control tool 
dedicated to this chipset?

The DMX6fire has both optical and phono SPDIF connectors, and a wavetable 
connector in the front box (for use with DB50XG etc), and works fine since 
1.0.12.
