Is there a tool that can be used to set the audio level stored in PRAM on Mac hardware? Can ntsetenv be used for this? I've found an init for MacOS that sets the stored audio level to 0 on reboot to supress the boot-chime, and sets it back up on boot, and I thought it would be nice to have the same setup for Linux, since the boot-chime can be annoying to others when working in a public environment. -raf
