Well, I did have some things messed up with my alsa mixer settings, but with
your example commands below for using arecord and aplay, I was able to get
them correct, so now arecord will record from the microphone and aplay plays
the recorded file...but...still nothing when I start ices2.

Do yave any next steps for debugging?

I really appreciate the help!
