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 termtech AT rogers DOT com. Thanks.
