  "sndio data stream" is linear PCM audio data.
  That can be played in any audio player out there.
  Why do you want to convert it to a RTP stream first?

  I cannot quite parse your sentences.

I think the original question might have better phrased as: How do I
forward sound and X from OpenBSD to Windows? Leaving particular tools out
of it. The natural tendency to include a tool that solves part of the
problem rather than restate the problem /de novo/ can bite us. --Ed

Thanks a lot for reply.

Now I want to know.
How to convert "sndiod data stream" to "RTP(rtmp/rtsp) data stream".
mplayer and vlc can recive the "RTP(rtmp/rtsp) data stream".
it will be so useful.(and so excited)

And,recently I get to know "module-sndio".(code like this)
"load-module module-sndio device="snd@hostname_of_my_rpi/0" record=false 
playback=true"
probably, these behavior will get "waiting the sndiod data stream on 
pulseaudio" on Windows.
If OpenBSD packages have "module-sndio", it will same too... 


I know, OpenBSD ports and packages "omit the any functions".
I accept it for the "OpenBSD's security policies".
I understood "If I can use the any useful factions. it is so lucky.".
Thanks a lot "OpenBSD maintainer".

I just ask any questions. not complaints.

best regards.

Yes, I think you got it backward on your previous mail; it's easy to
confuse one end for the other in these cases ;-)

I don't see any reason why it shouldn't work.  My point is that
pulseaudio itself is *not used* on most stuff you'll find on OpenBSD.

OpenBSD has its own audio stack and most programs (including the
majority of the music/video players and web browsers in ports) use
sndio.  So, configuring the forwarding at the pulseaudio level doesn't
achieve anything since firefox is not using it in the first place.

Yes, it looks correct.  Depending on your workflow you may want to
export AUDIODEVICE from ~/.xsession or even set things up so it's
always defined for you user in /etc/login.conf

Yes, that's because on FreeBSD and Linux it is more usual to have
pulseaudio (or I guess pipewire now?) running.  OpenBSD instead tends
to use sndio, by default at least.

I guess that it should work on OpenBSD too, but the majority of the
programs are not using pulseaudio.  I *guess* that you can configure
some programs to use pulseaudio if you really must...

(no idea how to do that however, I tend to avoid pulseaudio if
possible ;-)

Well, on FreeBSD and some Linux distro you can install and run sndiod
from their package managers.  That leaves out Windows though.  Maybe
it could work via the linux subsystem thingy (but it's just a guess --
I don't have any Windows machine.)

I think "I have any miss understanding for sndiod with -L- flag" correct ?
and, pulseaudio "native-protocol-tcp or RTP" doesn't work on The OpenBSD ?

[OpenBSD remote: 192.168.2.5]
## x11vnc with fvwm runnning on Xvfb by xenodm
## and could browsing the internet by firefox-esr
## if transmit sound to [*BSD or Linux LOCAL:192.168.2.10]

[*BSD or Linux LOCAL:192.168.2.10]
## waiting the sound data by the sndiod
## just do it...these command.
sndiod -L-

these are correct?

I know "windows doesn't have sndiod ports and doesn't work sndiod.".
Already I tried pulseaudio running on FreeBSD and Linux (include in Android, 
Raspberty PI) with Windows.It could get a sound by pulseaudio...

pulseaudio is transmit the sound data. between the *BSD and Linux or Windows...
I think "OpenBSD could too."...
and /etc/pulse/default.pa have a any modules by install the packages on 
OpenBSD...

Almost always I use the OpenBSD...
a few time use the Linux or Windows for somebody's tasks(include in "connect 
the my machine by VNC")...
And "Any time need a sound."...

I want to any ideas...

best regards.

I confirm, there's no windows port of libsndio.

I might be wrong but firefox shouldn't be using pulseaudio on OpenBSD,
so tunnelling it doesn't do anything.

I'm also not sure you're doing the sndiod remote audio thingy
correctly.

(see )

You should be running sndiod with the -L- flag on the system where you
want to audio to be played (i.e. windows in your case -- don't know if
there is a port of sndio for it or if it could work with the linux
subsystem) and run

$ AUDIODEVICE=snd@192.168.2.10/0 firefox

on OpenBSD so that the audio is sent thru your lan and being played on
your Windows machine.

Unfortunately I don't have the slightest idea whether sndio runs under
Windows; I've only did something like that with a rpi3 running linux
and it worked fine :)

how to transmit desktop sound on xenodm.

[openbsd_send]

Dear everyone.
I have any Questions for sndiod and pulseaudio.

I tried [OpenBSD Remote] to [Windows Local]...
but, I was never to get success...
how can i do it...

I am using X11VNC by Xvfb...
I want to get Desktop sound...

have any ideas?
