[grc] What sound card worked best with Rivendell for you?

[Max]

I'm building a Rivendell box and it's a server that our chief volunteer
thought would be robust and keep going. So it has no Mobo sound card and
we'd need 2 for Rivendell anyway.

So what's y'all's experience WITH PCI-E sound cards for Rivendell?

Does it have to be better than a 5.1 channel in your experience?
If so, what cards gave the best dynamic range and surge resistance and
impedance mismatch tolerance and good drivers support in Linux especially
Debian ?

Thanks!
