I have same setup as you, I recently did a clean install of FC2 with
Myth 0.16, and took me longer than usual to get my bttv card to have
sound as well.  Likely due to not remembering what I muted/unmuted in
alsamixer.  In the end my problem was I needed to mute the "line in as
center" in alsamixer to turn this feature off.  Check that setting.

Both my cards are set to /dev/dsp fine.
