The volume of beeps from firmware and pcspkr is fixed, it's not changed by any available mixer setting; the only thing that affects those beeps is Master Mute Switch, which mutes them both on the speakers and on the headphones. And one more thing - both beep types are audible on the headphones even if Headphones mixer is set minimum and Headphones Mute Switch is set to mute (if Master is unmuted, obviously) -- Regards Jarosław Janik
