OK, with my ~/.asoundrc file moved out of the way (but with the fixed
config file installed):

# aplay /usr/share/sounds/login.wav 
ALSA lib pcm_direct.c:901:(snd_pcm_direct_initialize_slave) requested or auto-format is not available
ALSA lib pcm_dmix.c:876:(snd_pcm_dmix_open) unable to initialize slave

# aplay -D hw:0,0 /usr/share/sounds/login.wav 
Playing WAVE '/usr/share/sounds/login.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
aplay: set_params:900: Sample format non available

# aplay -D plughw:0 /usr/share/sounds/login.wav 
Playing WAVE '/usr/share/sounds/login.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
  <no sound, but aplay sits there as if it was sending sound to a muted
  speaker and exits after approximately the amount of time for the wav
  file would take to play>

Is moving ~/.asoundrc out of the way sufficient?  Or do I need to
reboot or logout/login again to clear something?  I don't think there
are any user space daemons involved here, but...

Hmm, I don't know.  I'm not setting a reply-to header.  My e-mail
messages do have an SMTP envelope from field of tytso@...nk.org, but
that shouldn't be visible to MUA's.  (It just means that MTA's send
bounce messages to tytso@...nk.org, which I need to do since my
outgoing e-mail path goes through thunk.org, and if I didn't do I
might trip certain spam filters which check to see if the domain of
the SMTP "MAIL FROM" matches the domain of the sending SMTP server.)

In any case, my outgoing RFC 822 message headers on my end looks like
this:

It might be interesting to see what you receive it on your end.
