You still haven't described your hardware.  It might be a model that
people already know of solutions for, if only you'd say what it is.

I don't know.  And I Don't know if it'd come through, either.  You can
send a sample to my (generally) ignored mailbox, if you like.  You'll
need to insert the words "flying" and "pigs", together, without any
spaces between them, somewhere in the subject line to get past my mail
filter.  I'll only bother to check the mailbox over the next few days,
unless I'm prompted to.

While I may not be able to help you get sound working, I should be able
to tell you if it is recording bad and playing fine, or vice versa.

It's possible that it's just playing back back badly.  Recording might
be okay, or bad, too.  By "other-recorded," I mean sounds not recorded
on your hardware.
