What I do is running pulseaudio on all the computers in the network.
On one computer pulseaudio combines several sinks via tunneling to the
pulseaudio servers on the other computers. I use paplay on the first computer
with the combined sink provided by pulseaudio. So the client and server are
all pulseaudio.
Is there another solution to play sound synchronously to several other
computers without tunneling (and without RTP multicast which I found worse)?

E.g. with ogg123 it's possible to specify multiple pulseaudio servers
but of course it's not synchronized.

Thanks for your help,
