<pre>To reproduce:
1. Have two computers, one connected to speakers (the server) and the other
running VLC (the client)
2. On the server, append the following two lines to /etc/pulse/system.pa, start
Avahi, and run pulse --system --daemon:
load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1;192.168.1.0/24
auth-anonymous=1
load-module module-zeroconf-publish
3. On the client, append the following two lines to /etc/pulse/default.pa,
start Avahi, and run pulse --daemon:
load-module module-native-protocol-tcp
load-module module-zeroconf-discover
4. Run VLC on the client, observe the values returned by pa_stream_get_latency
in the function vlc_pa_get_latency in the file vlcpulse.c
Expected result:
Values vary within a relatively small range (which is what happens when playing
locally).
Actual result:
Values increase directly with time (i.e. after 4 seconds, values are roughly 4
seconds higher than they were initially).</pre>
