Hello everyone, This one has been bugging me for a while and I original put it down to using the preview builds of Windows. But I now have clean installed with the Windows 21H1 as of 22/05/2021 a...
What's your CPU/GPU utilisation during a call?
Also might be worth testing your network for packetloss, try running an assessment using Download Skype for Business Network Assessment Tool from Official Microsoft Download Center
Hey StevenC365
CPU and GPU are at a nominal usage level, with CPU at approx. 5% to 10% during the teams meeting
I haven't seen the GPU go above 50% and it is nominally at 10% utilization during the call (4K monitor, usually have GPU bound programs in the background).
After running the Network Assessment Tool:

It would be useful to look at the Call Records that your admin will be able to do through Teams Admin Centre, dig through the details. It's a puzzling one TBH, as your preview is working perfectly it's unlikely to be the camera or USB bus, network looks fine during that test (might be worth repeating). Also clearly audio packets are getting though just fine.
I'm slightly interested by your comments about disabling QoS, is there something on your network that might be changing traffic between you are the internet?
Hey StevenC365
I am the admin for our tenant. What report in particular should I pull down?
I also did a few other things to my physical network to eliminate anything by having my machine directly connected to the router. The QoS is the only thing that may have impacted the network packets (hence disabling as a test). The other part, is being an electron app, I would have thought that the web version would use the same protocol to transmit the video stream.
In the morning I will try a few tests with the logging for meeting diagnostics enabled and post the results from there.
I will also try and bypass the router tomorrow as well.
