That's the correct way to do it.

That is the result of the following line:
http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/module-combine-sink.c#n229

Basically difference between the estimated rates of the two sinks is
so great that resampling one of the streams to match the other would
probably not be a good idea. It seems there is something not working
right with the tunnel.

Have you tried it over wired lan connection?
The more verbose output of pulseaudio -vvv when this occurs would be
nice to have.
