<pre>Intermittently, when playing over network using module-native-tcp, an error in
transmission will occur. It is as yet unknown what exactly triggers this, but
it appears in multiple client programs. At this point, the server will log a
large number of "Client sent non-aligned memblock" errors, e.g.:

The session then becomes unrecoverable, and audio will refuse to play until the
client is restarted. It also appears to freeze the client network thread,
leading to some degree of unresponsiveness in the client program itself.
The version of PulseAudio in use is 6.0 on both client and server.</pre>
