I can't recall whether there was an AUX-IN option in alsamixer.  I'll
explain why "remembering" is important below.  However, theoretically, what
your saying makes sense.

I can't recall.

That was what I'd heard and I was trying to get everything via my soundcard,
but was struggling to do so.

In any case, thanks so much for the prompt reply.  Unfortunately, when I was
trying to fix this, I completely hosed my Fedora box.  I'd been somewhat
frustrated with Fedora anyway, so I wiped it and put on Gentoo.  Talk about
frustration! <sigh>  I'm probably still a few days away from even being
ready to install Myth again, but I'll apply your advice when I do.

Thanks again,
David
