        for (uint32_t j = 0; j < n_ports; j++) {
            uint32_t priority;

            if (pa_tagstruct_gets(t, &s) < 0 || /* name */
                pa_tagstruct_gets(t, &s) < 0 || /* description */
                pa_tagstruct_getu32(t, &priority) < 0) {

                pa_log("Parse failure");
                goto fail;
