I thought that was an ICE1724, rather than 1712; I was mistaken, sorry.

Still, as they are the devices are non-functional at least on my card,
and I'm ready to bet that the same would happen on the Delta 1010 given
that the number of channels is not coherent (you try to open surround71
as 8-channels and it'll fail because this minimal card has 10; if the
1010 has the same amount of channels, it'll still fail).

Maybe there's a way to describe different ICE1712-based cards with
different configuration files so that the surround device appears only
on surround-capable cards? Or let the user decide whether to load them?

Having them present and failing is not really nice.
