PulseAudio over network using Avahi

I'm trying to use PulseAudio and Avahi to stream music to my Raspberry. I've set it up like in the wiki (https://wiki.archlinux.org/index.php/Pu … er_network), and my Raspberry publishes the service like intended (I can see the PulseAudio Server and Sink). Playing music on the Raspberry with cmus also works, as did a direct connection by setting the default server in my laptops client.conf to the Raspberry,but when I try to play anything over the network (Edit: using the avahi-module), it doesn't work (mpd crashes, mplayer tells me "Audio device got stuck").

When I run pacmd list-sink-inputs (while not playing anything), it tells me:

1 sink input(s) available.
    index: 0
	driver: <protocol-native.c>
	flags: DONT_MOVE 
	state: CORKED
	sink: 0 <alsa_output.0.analog-stereo>
	volume: front-left: 65536 / 100% / 0.00 dB,   front-right: 65536 / 100% / 0.00 dB
	        balance 0.00
	muted: no
...

When I'm trying to play something over the network(Edit: using the avahi-module), the state changes to DRAINED.
When I'm playing music on my Raspberry, I get a second sink-input:

driver: <protocol-native.c>
	flags: 
	state: RUNNING
	sink: 0 <alsa_output.0.analog-stereo>
	volume: front-left: 51118 /  78% / -6.47 dB,   front-right: 51118 /  78% / -6.47 dB
	        balance 0.00
	muted: no
...

Does anyone know how  to solve this? Or how to get rid of the DONT_MOVE-flag?

Edit:
I can also see the sink (and switch to it) with pacmd on my laptop:

 * index: 1
	name: <tunnel.alarmpi.local.alsa_output.0.analog-stereo>
	driver: <module-tunnel.c>
	flags: NETWORK HW_MUTE_CTRL HW_VOLUME_CTRL LATENCY 
	state: RUNNING
...

Re: PulseAudio over network using Avahi

Do you have the zeroconf modules loaded for avahi?

And does your pulseaudio server show up when you use the avahi browser?

Re: PulseAudio over network using Avahi

Yes & yes.
I added

load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.2.0/24 auth-anonymous=true
load-module module-zeroconf-publish

to my default.pa on the Raspberry, and the same but with module-zeroconf-discover on my laptop.

Here's the output of pacmd list-modules:

index: 9
	name: <module-native-protocol-tcp>
	argument: <auth-ip-acl=127.0.0.1;192.168.2.0/24 auth-anonymous=true>
	used: -1
	load once: no
...
    index: 10
	name: <module-zeroconf-publish>
	argument: <>
	used: -1
	load once: yes
...
