Sound does not work in Chrome
N.B. This is not a Citrix issue, it applies to all versions of Chrome from 79 onwards
Starting with version 79 Chrome runs audio in a sandbox, which does not work with Citrix Virtual Apps.
If you have the latest Chrome ADMX files, you need to set this GPO computer setting to disabled:
Google > Google Chrome > Allow the audio sandbox to run = Disabled
Alternatively, you can use a GPP to set:
AudioSandboxEnabled = 0 (DWORD)
