We have some Tinys in classroom setups where their audio/video output is sent digitally to a controller that passes it on to a monitor on the podium and to an overhead projector. The Tinys all use Intel Integrated Graphics (4600/530/630) with Windows 10 Enterprise x64. Sometimes, the audio switches to the computer's built-in speaker as opposed to the system's and room's audio. I have mitigated some of these occurrences by disabling the Realtek HD Audio device, through a GPO, which is what seems to drive the internal speaker and foreces Windows to use the Intel HD Audio out of no other choice. This doesn't always work. Turning Realtek off manually doesn't seem to stick in the Device Manager. Is there any way to disable it wholesale? I was not able to find anything related to that in the BIOS.
