Hello!

Can you please try Mudita24, a replacement for Envy24:
http://code.google.com/p/mudita24/

It is already available as a package in some distros.

I've been waiting for a test case like this!

With Envy24, the support of ADC/DACs was kind of hard-wired.
If it didn't recognize the ADC/DAC, well it just didn't show the tab.

So one of my priorities with Mudita24 quickly became supporting
 ICE1712 cards with as-yet unknown future ADC/DACs.

In that respect I rewrote the code to ask ALSA for all the important
 information about ADC/DACs, instead of hard-wired info.

Give it a try.
I do expect there might be some issues, being an 'unknown' ADC/DAC.
Perhaps some checkboxes missing etc.  ... ?
Let us know.

You can post here or always reach me at

Thanks.
Tim.
