Just so I understand your response, are you stating that the login sound
for a graphical user login should be _muted_?  If so, this is relatively
straightforward to test.  Simply move 
/etc/udev/rules.d/85-alsa.rules, and reboot.  Is the login sound

Yes and no.  Yes as in the current scheme uses /etc/init.d/alsa-utils
(invoked from the above udev rule) to forcibly set as many matching mixer
elements as possible.  It does not require a user to login.  No
as in this scheme has its drawbacks as outlined in the original post.
