I am trying to change the startup sound. When I checked the setting using:
sudo nvram -p
it returns a setting for SystemAudioVolume DB %ee
sudo nvram SystemAudioVolume=%00
When I check again using sudo nvram -p
both names show up in the list:
SystemAudioVolume DB .... %ee
SystemAudioVolume .... %00 (it took my setting but doesn't kill sound)
Should I be trying to set SystemAudioVolume DB instead?
If yes, is this the right way?
sudo nvram SystemAudioVolumeDB=%aa
(No space before DB.) Does anyone know the proper range for this? My computer is old but I don't want to break it.
