TRX seems to work OK,  seamlessly integrates with ALSA, minimalist RTS protocol 
KISS style wins the day.
Took me a moment to twig that a local IP address must be specified on the 
receiver if the host's IPv6 interfaces have been knobbled (which mine have).
Not yet got the audio quality/rate quite right yet (want it lower) but plenty 
of scope to play with in the settings.

Not sure it's something similar that you are looking for, but take a look

Never tried, but I have a project coming up that requires exactly this.
I suggest you avoid getting bogged down in Desktops and complexity which has 
little to do with sourcing audio streams.

My first google turned up this...
http://www.pogo.org.uk/~mark/trx/streaming-desktop-audio.html

if you try it please post how you get on, as I intend to go down this route you 
could save me some work :).

I've always interpreted that as sound from the remote machine coming to me, 
but not including a microphone on my machine getting converyed to the other 
end.

Nor me, usually, but this is a simple thing for me to try (since I already 
have KDE at both ends) so I'll see what it does.

Hi,
Krdc (Kde remote desltop client) has a setting:

Sound: on this computer / Remote computer /disable sound
and Alsa/Pulseaudio/None.

Cannot say if it does what you want as I don't use audio in remote
desktop sessions.

Ciao,
Tito

I've used netJACK1 for this in the past. On the machine with the sound
device, you run a regular JACK daemon, plus jack_netsource. On the other
machine, you run the JACK daemon using the "net" backend, and tell it to
connect over the network to jack_netsource. The netsource shows up as a
JACK client on the main machine so you can connect it to whatever
inputs and outputs you like, and the network connection only adds one
JACK period's worth of latency.

The major downside of this is that it's only useful for applications
that can use JACK for audio (which is most pro-audio stuff, plus a few
others like mpv). If your applications only talk PulseAudio, you'd also
need to configure PA to use JACK for input and output; I haven't tried
this myself.

Cheers,
