I followed the vMix tutorial vMix and Zoom integration to integrate VMix and Zoom meeting. Everything works well except that the VMix A bus Audio which is integrated into the VMix NDI external output is distorted with pops and clicks and also a noise floor.

When I monitor the VMix A bus, the audio is very clean so the distortion must have been introduced during creation of the NDI output stream.

Is there any way to troubleshoot and fix this or is this a VMix fault?

Thanks for your help.

Unfortunately not. No guidance from vMix support. I now use NDI for video only. I use VB Audio cable on the A bus to send to Zoom. This has worked flawlessly. I think vMix needs to update their video.

Hope this helps.

Hi,

I encountered similar issues while streaming to Zoom.
I also thought his was a vMix issue, however after a lot of research I found that there are Zoom settings thank can fix this(audio/advanced).
You can increase audio quality, get rid of echo cancellation but most importantly check-mark "Show in-meeting option to Enable Original Sound from microphone and then enable that function in the meeting itself.
Good luck

In my studio we recently started getting pops and clicks over the digital Dante network (Virtual Sound Card). Maybe the same issue you are having. There is app called LatencyMon that tests your systems suitability for real-time audio tasks. Mostly, the issues were with our high end gaming laptops that had either outdated graphic drivers (after a Windows Update) or with the performance option within the NVIDIA control panel. It was causing huge buffer underruns that caused latency in the audio stream...or something like that. Anyway, once we got the system tuned using LatencyMon the audio was crystal clear on Dante.
