[Alsa-user] Card information?

[Brett I. H. <bre...@ch...>]

I have a Turtle Beach Santa Cruz card with a CS4297A chip.  When I run a 
mixer there are many controls such as 3D control, some IEC958s, two PCMs, two 
CDs, and more.  Where do I find out exactly what these all do?  I've checked 
the Alsa site but it doesn't have much - just generic install instructions - 
and I haven't found any other docs that tell me what these are for.

Thanks.
