hmmm... i think i just solved my problem.  it was axel's hint.  i did a
verify and both the dmix.conf and dsnoop.conf didn't match the rpm.  i
re-installed the alsa-libs rpm and suddenly myth sound works!

i looked at what was there in /etc/alsa/pcm.  there had been a couple
of .rpmnew files there before, and i think i must have assumed that they
were from the new installs.  they weren't.  the .conf files matched
the .rpmnew files, so were from some prior install.  i must have missed
the rpmnew files when i went through cleaning up that kind of stuff last
time around.

thanks for the hint axel!  thanks all for the hints and thoughts.

so.  one mystery solved i guess.
