I have users in my lab that run sound via their speakers. I would like to disable the ability to do so on all machines in the lab to prevent this, whilst still allowing them to use their headphones.
I have read articles about how to disable all audio (not a totally desirable outcome, but better than the alternative) by deleting the IOAudioFamily.kext file, however, this doesn't seem to work on High Sierra.
Has anyone aware of a solution to this issue?
Thank you for your help.
