vban_emitter does not receive any sound from pulseaudio device

[inoculator]

Hi. I try to archive to have audio from a linux workstation (Mint) to a windows machine. I have created a sink "DDVOut1" that is displayed in pavucontrol and I can assign audio from applications to that. It also shows audio level on the bar. I start "vban_emitter" and the recording device pops up in pavucontrol. I assign the corresponding monitor to it and the level bar begins to show sound. On the receiving VB-Audio Meter (Potato) the VBAN Stream gets a green light and the Sampler shows the correct values. Nevertheless no audio is coming from the system. If I look into Wireshark, I can see the traffic, but there is only "zero" in the data, so no Audio seems to be received at process level on the sending machine. Here my sets:

 ~ $ pacmd load-module module-null-sink sink_name=DDVOut1
 ~ $ pacmd update-sink-proplist DDVOut1 device.description=DDVOut1
 ~ $ vban_emitter -i 10.10.10.238 -p 6980 -s DagobertDuck -b pulseaudio -r 48000 -l 3 &
[5] 5890
 ~ $ vban_emitter version 2.1.0

Info: socket_open: opening socket with port 6980

Info: audio_set_map_config: new map config is nb channels 0

What do I miss?

Hi, sorry for the long delay in answering. If I am not mistaken the fact there is no color on the volume bar of your vban recording device + the loudspeaker button being "down" means that it is muted.

Hi, I have played around a while and for some reason I cannot replicate, it is working now. I created a file like so:

#!/bin/bash

##Emitter

pavucontrol &
pacmd load-module module-null-sink sink_name=DDVOut1
pacmd update-sink-proplist DDVOut1 device.description=DDVOut1
vban_emitter -i 10.10.10.238 -p 6980 -s DagobertDuck -b pulseaudio &

##Receiver
pacmd load-module module-pipe-source source_name=DDVin1 file=/tmp/DDVin1 format=s16le channels=1 rate=16000
pacmd update-source-proplist DDVin1 device.description=DDVin1
vban_receptor -i 10.10.10.238 -p 6980 -s Microphone -b file -d /tmp/DDVin1 &

and both signals work. This setup has now been in place for about 2 or 3 weeks and as I do not use it on a daily base, I did not dive deeper. Nevertheless since yesterday, when trying to establish some SIP Clients (egika) suddenly the receptor is sending back the stream via the emitter, so that I can hear myself speaking with a slight delay. The trigger point seems to be some loopback I loaded, but unloaded later on. the Loopback itself seems to stay, whatever I do:

pacmd load-module module-loopback latency_msec=1
pacmd unload-module module-loopback

Even I do not think, that it is a VBAN issue, I place the question in here, if this is somehow known?

Otherwise, this issue can be closed from my point of view, as the original question has gone obsolete.
