description_key is set in pa_alsa_path_new():

    items[0].data = &p->priority;
    items[1].data = &p->description_key;
    items[2].data = &p->description;
    items[3].data = &mute_during_activation;
    items[4].data = &p->eld_device;

    if (!paths_dir)
        paths_dir = get_default_paths_dir();

    fn = pa_maybe_prefix_path(fname, paths_dir);

    r = pa_config_parse(fn, NULL, items, p->proplist, p);

pa_config_parse sets the description_key either to NULL or to some
malloced string. If the alsa mixer path doesn't contain a description-key it will
be NULL.
