I'm posting and asking for guidance for a project that is now deep in the red. I was recently engaged in the last week as an escalation of last resort. I'm coming from the Citrix Architect perspective and although the backend hardware is heavy-duty it is considered in the development phase which apparently equates to no support from the SAP customer perspective. I'm not sure where to begin other than we are making poor progress with this GUI (used Patch 3, 4, 5, and now 6). 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.SAP 760 GUI for Windows Patch 6 Server 2016 & Citrix PVS Streamed Shared VDI - 'Too slow and it should be faster' 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.
