Answering to myself: Installing sox.tce gives the play command, A part of the freedesktop theme sounds i found on sourceforgenet. Now, play sound.ogg
obviously created a problem to alsa: Although the sound is played, i get this error msg (or warning):
$ play desktop-login.ogg
play WARN alsa: can't encode 0-bit Unknown or not applicable
desktop-login.ogg:

Any ideas in regard?
