Sorry I wasn't clear.  I saw the code for the opening of the command line 
driver in audio_out.c, but was wondering why the default order of opening 
was to use "native" first then "wrapper".

BTW, the -ao option is not discussed in the section of the manual under 
"command line".  (It is in other places.) Again, I'll be happy to add it 
if that's what people want.

I am using mplayer for the playing of audio files (since FC4 comes with 
MP3 configured to play under noatun, which cannot in fact open mp3 files - 
at least as it's supplied by default).  In this case, synchronization is 
not an issue.  Might it not be best to change the default behavior if what 
is being played is an audio only file to use the wrapped drivers first?

Also, the messaging from the crash on unpause could be improved to make it 
clear what really happened and what should be done to fix it.
