 From this I deduce, somewhat clumsily, that you (normally) have ALSA
running but not any of the others. If this is not correct, please tell
me.

All I can say is that the error message "Could not open/initialize audio
device" means, to the best of my knowledge, one of three things: that
there *is* no audio device (plainly not the case here), that it is not
configured with the correct drivers and so forth (also not the case
here), or that some other program has locked the audio device for its
own use.

The most common thing to have running which locks the audio device is a
sound daemon, ALSA/Arts/ESD or similar. MPlayer is capable of using any
of these, with the correct -ao method; if none of the available -ao
methods function, then I honestly don't know what to suggest (other than
that it *might* be a bug in your -ao driver, if you seriously think that
that MPlayer must be the source of the problem).

Sorry I couldn't be more helpful.
