    dump-aio-position gives only selected aio position.

    dump-status does this.

    The dump-commands have been useful in my ecasound-frontend at reducing the parsing of ecasound normal output. You have to, however, to request the dumping, there's no automatic 'when value
changes' dump-objects. I don't know if it would be worth the effort to extend the dump section with commands like: dump-object-add <value-to-dump-when-changed>, or to have multiple dump-targets.

    Depends on you Kai, but I guess at some point it would be easier to go straight to libecasound. How is it going with the C-api? :)
