I don’t hear the sound of my Mac on TV, does it interfere with the Boom2Device audio driver?
Yes, we have had numerous users who experienced a problem with getting the sound from the Mirror to TV app on TV because of a conflict with the Boom2Device audio driver.
Best is to uninstall this driver, this is how you do it:
Open Terminal app and run the following command(s)
To remove BoomDevice:
sudo kextunload -b com.globaldelight.driver.BoomDevice
To remove Boom2Device:
sudo kextunload -b com.globaldelight.driver.Boom2Device
This should do the trick and you even don’t need to reboot your Mac.
