Chromium Audio Sandbox Removal
So previously we had to disable the Audio Sandbox in Chrome and Chromium browsers, including edge, to get audio in published applications.
With updated VDAs it looks like this is no longer the case, so if you are using my template GPOs, make sure you remove that setting with later VDAs.
