Hi,

I have a strange issue with some Wyse 5070s, where during a Teams call, if a user shares their screen then the audio quality suddenly becomes very poor.  HDX Optimization is in use and the audio works fine (using a straightforward Jabra USB headset), until you share your screen.   Immediately the audio cuts in and out every second or two, and/or 'robot-voice' distortion, making it very hard to follow a conversation. Stop the screen share, and the voice quickly comes back to normal.  If you disable HDX Optimization then the effect goes away, but obviously the quality is worse anyway.

We tested today using a PC to connect to the Citrix machine (same Citrix session), that could share it's screen without any audio problems.  So the problem seems limited to the Wyse terminal rather than a Citrix issue.

We have lots of network bandwidth and Performance Monitor on the Wyse is only showing about 15% CPU utilised and almost no RAM used, so this looks more like a software package problem to me.   Everything is up to date with the new BIOS, ThinOS and Workspace that was released on 7th Sept, though I've tried the previous versions and it behaves the same.

Anyone else come across this, and have any suggestions?  I tried a 3040 we have lying around too, same problem on that as well.
