1. Go into the Hijack menu, and select the "Volume Level on Boot" screen.
2. Select "Previous" as the setting, which will restore whatever volume level was previously in use (at poweroff) on the next boot ("normal operation"). Press Menu/Knob to save the setting.
3. Exit from the Hijack menus.
4. Dial the volume you want it to restore to, be it 0db, -40db, or whatever.
5. Go back into the "Volume Level on Boot" screen, and change the setting to "Current". Press Menu/Knob to save the setting.

Repeat the above for each of AC/DC (while running on the appropriate power source, or using Force AC/DC from Hijack) if desired.

EDIT: I'll welcome suggestions for better settings labels (within screen confines)

Cheers
