The sound the GDM plays when you've enabled audio. It plays after login,
which is nice. But that doesn't meet the user need to know when GDM is
ready for use.

I suspect no one thought to give this feature a name. If they did, I
haven't heard it. Typically a Marketing Dept would call such a thing a
"audio logo." Think of the sound that accompanies Intel's "Intel Inside"
commercials.

Sorry, I don't recall that--nor can I find it in my mailboxes or via
Google. I do see an extended conversation on gdm-list that included both
of us. Looking at that mail I see that I reported this sound would play
after a Ctrl+Alt+Backspace--but not on boot. That continues to be the
case.

I don't necessarily. Again, the user need is to know when GDM is ready
for login. A beep on backspace is one way to achieve that. It was the
old behavior when "SoundOnLogin=TRUE"

OK. Thank you. Ctrl+s to start Orca with speech, Ctrl+b to start it with
braille, and ctrl+m to start it with magnification are certainly
noncontroversial. We discussed additional, mouse-oriented a11y for users
of Gok on gdm-list. I don't believe we came to conclusions.

Orca makes no decisions about audio devices. Neither does gnome-speech.
So, it's rather an uncontrolled hand-wave.

Perhaps not, but commenting and uncomment line 11 in
/etc/alsa/alsa.conf--the line that invokes (or blocks) pulse audio
toggles this between broken and correct functionality. What else am I to
conclude about pulse audio?

Well, my apologies if this offends you. Is it supposed to work that way,
though? Is there actually a use case for that behavior? Or is this just
some incidental artifact?
