These non-persistent desktops are reverted to their original state, in Windows current 1 this change happens when a virtual machine goes through a shutdown/restart/OS reset process and in Windows down-level 2 this change happens when a user signs out. Non-persistent versions use a collection of desktops that users can access on an as needed basis. These unique desktops can be customized and saved for future use. Persistent versions use a unique desktop image for each user or a pool of users. There are two primary types of virtual desktops: Deliver end-users mobility and the freedom to access virtual desktops anytime, from anywhere, on any device.Reduce costs through consolidation and centralization of resources.So, if a new version of CWA is deployed in the mean time, they might just disconnect for the update, reconnect and find that the audio does not work anymore.Administrators commonly deploy virtual desktop infrastructure (VDI) platforms hosting Windows operating systems in their organizations. This might seem like a minor thing, but the users I support are used to just disconnecting from their VDIs and stay signed in for long periods. Luckily, its easily fixed by signing out and signing back in to a fresh VDI. That means, there could still be a very minor issue here, popping up when a user disconnects their session, upgrades CWA and connects again. I only tested by adding the key, disconnect and reconnect again. That the audio came back when I added the registry key to disable Adaptive Audio also probably threw me off from the real issue. These are random pooled VDIs, so the new VDI I signed in to has been running all the time. Nothing else was changed on the VDI-side.

A fresh sign-in to a new VDI in the same pool fixed that issue. So something was set on the VDI from when I used the older version of CWA, and that didn’t reset when I reconnected with the new version. So when I connected again with my upgraded CWA, Adaptive Audio was connected but didn’t work. I must have only disconnected from the session during that upgrade, and not signed out completely. I first saw this issue after upgrading CWA on my work computer. I most have forgotten the basics earlier, always from scratch when you have an issue. To make sure I really was starting fresh I did a reboot of the VDI, logged back in… and adaptive audio works. I thought I’d do a bit more testing, just to see if I could find a different angle to solve the problem.
