If you don't have time, you could simply prefix the the aplay command
with "sleep 2s;" to give yourself a little more time to prepare :D

But random data (which is what .ogg files look like to aplay) is as good
as anything for testing (even if it does sound horrible!) to that is all
fine :)

Yes. It means the "default" alsa device is not mapped to the alsa-pulse
plugin.

We detail this here:
  http://pulseaudio.org/wiki/PerfectSetup#ALSAApplications
(see the section starting "If you want to make the PulseAudio driver the
default....")

That said, this is really something your distro should configure for
you, so I would very much go and complain to them and tell them that
"your default alsa device is not configured to be the alsa-pulse plugin."

Hope that helps.
