serveur de son pulseaudio

Bonjour,

je souhaite me faire un serveur de son pulseaudio, mais j'ai beaucoup de difficulté à trouver de la doc (à part sur le site pulseuadio mais c'est vraiment basique) et je rame un peu :

1- le serveur tourne sous debian squeeze, sur un dockstar (arm),, pulseaudio fonctionne en local avec mpd pas de problème

2- les clients sont sont ubuntu, je souhaite donc envoyer le son de mes PC client vers le serveur pulseaudio (dockstar)
et là j'ai quelques soucis, quelqu'un à déjà mis ça en oeuvre ?

coté serveur (dockstar):


carte son USB terratec Aureon

aplay -L

### Alternatively use the static hardware detection module (for systems that
### lack udev support)
load-module module-detect

### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluetooth-discover.so
load-module module-bluetooth-discover

### here if you plan to use paprefs)

load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.1.0/24

### Load the RTP reciever module (also configured via paprefs, see above)
load-module module-rtp-recv

### Load the RTP sender module (also configured via paprefs, see above)
#load-module module-null-sink sink_name=rtp format=s16be channels=2 rate=44100 description="RTP Multicast Sink"
#load-module module-rtp-send source=rtp.monitor

### Load additional modules from GConf settings. This can be configured with the paprefs tool.
### Please keep in mind that the modules configured by paprefs might conflict with manually
### loaded modules.
.ifexists module-gconf.so
.nofail
load-module module-gconf

### Automatically restore the default sink/source when changed by the user during runtime
load-module module-default-device-restore

### connected to dies, similar for sources
load-module module-rescue-streams

### Make sure we always have a sink around, even if it is a null sink.
load-module module-always-sink

### Honour intended role device property
load-module module-intended-roles

### Automatically suspend sinks/sources that become idle for too long

### Enable positioned event sounds
load-module module-position-event-sounds

### Cork music streams when a phone stream is active

coté serveur j'ai ajouté le user dans le groupe audio


coté client,
j'envoier un flux RTP multicast (configuré via paprefs)
je vois le flux audio RTP arriver sur le serveur dockstar, mais je n'entend qu'un crachouillis désagréable
sans doute un problème de conf entre alsa et pulseaudio sur le serveur (dockstar) mais là je ne vois pas


en fait je suis un peu perdu concernant la conf d'un serveur pulseaudio ?

si quelqu'un à déjà mis ça en oeuvre ça m'intéresse


merci
