Well, it turns out that there is a problem with the code that chooses
play_command.  I totally missed it yesterday!
Here is src/modules/generic.c, line 396:

                }else{
                  assert("Unknown audio output method requested");
                }

The assert call aborts the program if a condition is false.
In this case, the condition of the assert is just a string, and that's
always true, under C's definition of truth.  The process doesn't terminate
when it decides that your audio output method is unknown.

I'm going to send a patch for this one, later.
One approach is to default to "play" for play_command.
I think that the play program is commonly available.
It should be a reasonable default.
The other option is to print a warning and call abort.  That seems to be
the intent of the original code.
