These laptops all have the codec of alc285.

reproduced by:

        1. Hookup a set of headphones that you can separately place
        in/on your ears. (ie. ear buds)

        2. Put only the right headphone in/on your ear.

        3. Go to the Gnome sound settings and bring up the "Test
        Speakers" function

        4. Play the left speaker test

        You would expect to hear nothing in the right ear, but instead
        you hear a "pop" at the start of each word spoken. ("pop"
        Front "pop" left). You can repeat with the left headphone and
        see similar results. I even tried shifting the balance all the
        way to the left/right and get the same results.

        So one problem appears to be when the headphone jack is
        initially sent audio, it causes a "pop" in the headphone jack.
