Are you in csh/tcsh?  If you're in a more "normal" shell (bash or zsh),
that set command doesn't do anything useful.  Certainly nothing that
would affect the play command.

Even if you're in (t)csh, my understanding is that "set" sets shell
variables, and you need "setenv" to set environment variables (which
could conceivably affect the play command).  So, even in (t)csh, I
don't see how your set command is supposed to work.

Other shells... rc? fish?  I don't know these.  I have no idea what
the set command does in them.
