Motorola Xoom :: Power On Button & Sound Out?

on mine XOOM /WI-FI tab, it seems that i need to first push the on button then let go an push an hold again for a sec then it will power on? Is this the normal way to turn on from a total power off state? As in sleep mode only need to be pushed 1x and screen comes awake. There actualy is nothing of any extent on the power button in the emanual that I could see for normal power up.Also as iv seen some comments elsewhere on the Sound Output quality, well on a set of earbuds its good quality sound, on the built in speakers ..well for a device of this small size one should expect decent sound but cant expect very much as to high end sound really it is only tiny sound. But ..the HDMI out sound is very poor quality , on a TV in or AVAmp in the same..very flat, dulll, boxee sound-tested using same music vidaudio file as from laptop, or other small device. and resulting sound is ..well crap... just only real neg comment otherwise.
