Instead of using pax11publish, you can do this on the remote computer:

    pactl load-module module-tunnel-sink server=YOUR_ADDRESS sink_name=tunnel_to_alex
    pactl load-module module-combine-sink sink_name=combined_sink slaves=tunnel_to_alex,LOCAL_SINK_NAME

Replace "YOUR_ADDRESS" with the address of your computer and
LOCAL_SINK_NAME with the local sound card sink name of the remote
computer.

This will create two new sinks on the remote machine. The first one is
named "tunnel_to_alex", and anything played to that sink will be
forwarded to your computer. The second one is named "combined_sink",
and anything played to it will be forwarded to "tunnel_to_alex" and the
local sound card sink.

If you're not sure how to find out what LOCAL_SINK_NAME should be,
"pactl list sinks | grep Name:" will list the names of all available
sinks. The local sound card sink name is probably something like
alsa_output.pci-0000_00_1b.0.analog-stereo.
