    mixer(8): Ignore mixer_open() failures for the -a option
    
    The most likely reason mixer_open() will fail is because either the
    device doesn't exist, or because it is disabled, so there is not reason
    to kill the application. Instead, continue and print the rest of the
    enabled mixers.
