> Remote microphone access with Windows RDP protocol is causing Guacamole connections to drop/close as soon as the redirected-audio (microphone) connection is accessed. I'm able to recreate the bug in all major browsers: Firefox, Chrome, Edge and IE11. The bug does NOT occur with native Windows 10 RDP client, so I've been able to narrow down the bug to Guacamole.
