Perhaps the patch below for mplayer is good enough?

libao2/ao_jack.c :

- for (i = 0; i < num_ports; i++) {
- if (jack_connect(client, jack_port_name(ports[i]), matching_ports[i])) {
- mp_msg(MSGT_AO, MSGL_FATAL, "[JACK] connecting failed\n");
- goto err_out;
- }
- }
+ for (i = 0; i < num_ports; i++) {
+ char portname[1000];
+ sprintf(portname,"%s%d",getenv("MYPORTS"),i);
+ if (jack_connect(client, jack_port_name(ports[i]), portname)) {
+ mp_msg(MSGT_AO, MSGL_FATAL, "[JACK] connecting failed\n");
+ goto err_out;
+ }
+ }
