Hi,
We have a problem on our VDI platform with USB headset, most of our users are Call Center user and need to good audio quality for their requets,
In normal cases, audio quality is good but when users wants to scroll a page in browser or use graphical applications and even using volume mixer, he faced with noise and in some cases vioce will be cutted off.
Based on my experince, it's not related to our resources, because we have enough resources and also we've checked it on virtual machines by increase CPU ferequancy, memory size, core per socket or etc.
Also we checked PCoIP vaiables on clients and hosts and use different values for FPS, initial image qulaity even we disabled BTL feature, but nothing changed.
This is a summary of my story 
Please advise me.
