I didn't want to get specific as it's not a use case for many others
outside of ham radio. Digital communications with ham radio is done with
a sound card and the audio is sent to the radio and transmitted over the
air where it is then captured and interpreted by the receiving station.
I want to simulate this in a meeting environment with two laptops
without radios.
I figured out a working configuration using rtp. Follow the same
process on both computers. Copy /etc/pulse/default.pa to
~/.config/pulse. Then add the following lines at the end of the new file:
load-module module-null-sink sink_name=rtpout format=s16be channels=2
rate=44100 sink_properties="device.description='RTP Multicast Out'
device.bus='network' device.icon_name='network-server'"
load-module module-rtp-send source=rtpout.monitor loop=0
load-module module-null-sink sink_name=rtpin format=s16be channels=2
rate=44100 sink_properties="device.description='RTP Multicast In'
device.bus='network' device.icon_name='network-server'"
load-module module-rtp-recv sink=rtpin
load-module module-remap-source source_name=rtploop master=rtpin.monitor
Run "pulseaudio -k" to restart pulseaudio. Now in the sound settings,
you can pick the RTP Out for the output and the Remapped Monitor of RTP
In as the input. I tested it with audacity and despite using the
default pulse input, it kept insisting on reading the microphone. So I
used pavucontrol to set its input to the right one. I was then
recording what I was playing from the other computer.
You could probably do this with one of the other transports as well, but
paprefs almost made this setup work, so I only had to add a bit more to
have it fully working.
