I try to change the start tone. When I checked the setting with:
sudo nvram -p
A setting for SystemAudioVolume DB% ee is returned
sudo nvram SystemAudioVolume=%00
If I check that again with sudo nvram -p
Both names appear in the list:
SystemAudioVolume DB ….% ee
SystemAudioVolume ….% 00 (accepted my setting but did not stop the sound)
Should I try to set SystemAudioVolume DB instead?
If so, is that the right way?
sudo nvram SystemAudioVolumeDB=%aa
(No place in front of DB.) Does anyone know the right area for it?
My computer is old, but I do not want to break it.
