I have a 32G that has been great for me. Got another 32G for a family member on my recommendation. When it arrived, there was no audio output to the speakers or the headphone jack. I can adjust the volume with the volume rocker and the display shows volume changing. I can toggle the mute and still no audio. Is this defective or am I missing something? Does Asus have a tech support #, can't find one on their web site. Thanks!
