Well so far Carl, I just have a no name Chinese un-brand. Actually have two different ones, but suspect probably the same chips and manufacturer.
Dirt cheap too < $10 each. Think they weren $5-$6 range a year ago when I started tinkering with them.
Might consider the fancier higher end models for tinkering later. Goal is to build and test rapidly and then improve things where feasible. There are tons of "high" end USB cards out there, but not financially available to many people today.
One of the cards looks very similar to this one:
Nice thing about USB is you can affordably run (given have CPU to do this) multiple cards. So in theory should be able to have one for line (phone, remote, etc), one for rendering final audio out to speakers and one for general mixing controls. That's my idea 🙂 Probably is overkill.
