Thanks. Will leave out "HWMIX" from the ICE1712/1724 card tags.

Thanks again, just added "RCAio" to the 6Fire.

You're right, just checked the manual. I see the driver creating a 8/16-bit 
8-48 kHz "ICE1712 consumer" PCM that I suppose will be the one that ends up 
at that backplate analog out. The "low-grade" will be fairly relative so 
I'll leave in the ANALOGio tag for the ES88D as well. If someone reading 
this knows better, please yell...
