I've been banging my head for the last 2 days.
I did receive complaints from the business I work in that during broadcasts the audio was wrong.
I did some digging.
on 2 new systems both installed with NDI5.
System 1 has VLC with the NDI plugin playing a music video
System 2 Studio monitor recording the stream. the audio is out of sync. and has unrecognizable spikes/pauzes in it.

I tried the webcam input. and only used the audio to input to Voicemeeter Banana. and did a recording that way.... same poor result.

I reverted back to NDI4 all issues solved.

I know. it is just a warning. and I use VMIX for my Live Events for the last year.

today I downloaded a newer version of NDI tools. 5.0.3.0
the initial issue I had was with 5.0.0.0
I will post an update if the issue is still there.

Out of my head:
Open explorer
Goto the program directory
Goto NDI folder
goto Stiudio monitor folder
Right click StudioMonitor application.
goto the tab details.
There you can see the version number

I tried 5.0.3.0 and it works. but I had to make sure that I have different settings.
Only the VLC plugin does give me issues. sometimes no audio at all.

But for VMix I have these settings on my system with MS Teams.

My Settings:
Control panel - Sound - Recording - Line (properties)
--Tab: Listen
----Unchecked - Listen to this device
----Playback: Default Playback Device
--Tab: Levels
----Line:100
--Tab: Advanced
----44100Hz (CD Quality)
----both checkboxes checked
Control panel - Sound - Communications
--Do Nothing

VMIX
--Settings
----Outputs/NDI/SRT
------Select your NDI source gear wheel
--------Audio Channel (for me Master. make sure you do a level check for other channels) Master
--------unchecked 20dB Boost
--Audio Mixer
--Audio source 100%
----master 33% -10dB

Newtek Webcam input
--select VMIX source as input
--Audio
-- +20dB

Microsoft Teams
--Do not join a call (yet)
--Click on "Settings and more" (the 3 dots next to your avatar)
--Click on Settings
--Click on Devices
----Speaker is my physical speaker output
----Microphone - Line (NewTek NDI Audio)
----Automatically adjust mic sensitivity - OFF
----Noise Suppression - OFF (pre windows 21H1) (low with 21H1) (otherwise loud static noise with low it is usable but not great)
----Camera - NewTek NDI Video

@mavik upgrading of VMIX to NDI5 is not related to this topic.
It is the NDI webcam that is the issue or the studio monitor or the vlc plugin.

The current version only supports lan configuration. Not yet over the internet.
So nice within the corp wan network. Between europe and north america.

Sorry that was bridge.


Remote not yet tested

Same here. Currently medialooks does NDI over WAN but adds extra cost that we all want to avoid.

For me, NDI5 is really unstable, its not production ready. I rolled back to NDI4.5 which is rock stable.

make sure both applications run in 48kHz

as your teams run in 44.1 but vMix is straight 48 only thismught be your issue.
