Well I can confirm after further testing that the 'Get Copied Text', and 'Paste Text' always appear after setting the appropriate group policy. I can also confirm that the sound also works after setting the appropriate group policy.
However the "Get Copied Text" functionality is inconsistent in its behavior. It went from working reliably to not working at all in most browsers.
If I restart the blast service on the Guest VM's, and reconnet the web client, then "Get copied text" works as expected.
Very strange. I guess I should open a ticket.
