There is nothing in the event viewer that could explain what's going on. It is very odd because most PCs are started up before the IWBs and the majority of the IWBs are functioning properly, I'm just hoping this is one of those things that resolves itself.

Hello, I am new to Edugeek, so apologies if I have posted this in the incorrect place. Our school uses VeryPC PCs in classrooms and a mix of SMART, Iiyama, Samsung, Sony interactive whiteboards and they're all connected with HDMI cables. Last week, 3 teachers reported that their interactive whiteboard stopped playing audio. I tried changing cables, ports, reinstalling audio drivers etc and couldn't get anything to work. Until I went into sound settings, clicked on the interactive whiteboard sound option and then changed the 'Format' option to the FM radio quality option and it suddenly started working again, temporarily. I then found that whenever opening a new window or even pausing a youtube video and unpausing it, would cause the audio to disappear again, until I go back into the 'Format' options and change it onto a different quality and then back onto FM radio quality. This is happening now on 5 whiteboards across the school (that I know of). All of them are VeryPC PC's running windows 11 and the whiteboards are a mix of SMART, Iiyama & Sony. This only started happening last week so I have no idea what could have caused this. I hope this makes sense to someone, because it's got me baffled. Any help would be greatly appreciated!
