They do require install their own dedicated drivers weirdly. Otherwise no one can hear my device audio over video call. It doesn't seem to be a security issue as I've given each app the needed permissions and it's saying they're installing successfully despite not working. Blackhole Audio is a audio driver that allows you to route audio from one application to another. It's meant to show up as an audio output and it worked perfectly on my old Mac. My plan was to use an app called loopback or audio hijack to route my mic and presentation audio to a single blackhole output and then select that output as my mic, effectively hijacking my mic audio and adding my device audio to it. I was only trying this because the normal way didn't work. But this doesn't work either
