[MPlayer-dev-eng] Bug: ao jack in libao2/ao_jack.c

[freacky22527 at free.fr]

With my version of jackd (0.100.0), mplayer always return the same error:
"[JACK] cannot open server" but jackd il lauched and works perfectly with
alsaplayer.
So i made a patch to fix it :)
cat ao_jack.diff:

241c241,242
<   if ((client = jack_client_new (client_name)) == 0) {
---
>   client = jack_client_new(client_name);
>   if (!client) {

patch ao_jack.c ao_jack.diff
compile and it runs ;)
