    I get a loud pop when plugging in headphones or turning on the sound after a delayed period of time. I've tried turning off drivers, updating drivers, turning off sound enhancements, and updating the BIOS. Nothing has helped.

    I measured the DC offset out of the audio jacks between ground and the L/R channels. One jack has offsets of roughly 1200 mV, the other has offsets around 6.4 mV (volume set to zero in both cases). The 1200 mV DC offsets seem a bit off the charts to me. I don't know what the acceptable ranges are for laptops, but the offset on my amp isn't measurable.

    Asus tech support hasn't been able to help me track down the problem. Does anyone have suggestions?

    Thanks!
