Smartboard Sound issue - red X on speaker
We are having an intermittent issue with our Dell laptops losing the Smart Board Sound driver when staff use a slightly different smartboard, this results in a red X on the speaker and the only way to resolve is logon as Admin and remove the Sound Driver in Device Manager.
We have a combination of 880 and 885 Smartboards using the CAT5-X USB Dongles
Staff move classrooms and may end up using both versions of the boards at some point of the day.
What seems to happen is the laptop re-installs all the drivers for the Smartboard and Speakers when the user docks the laptop. Every now and again the Speaker part fails and the red X scenario mentioned above occurs.
This makes no sense at all.
We have tried using Smartboard 11 software, latest firmware on both board and dongle.
I am stumped. Can you anyone help please?
