Comment:

 The fact that the click occurs about a half second after the button is
 pressed suggests that the problem is not the same hardware issue that we
 solved before. It is likely to be a driver issue.

 On my B3, I can auto-suspend/resume (using RTC to wakeup) with no sound
 from the speakers.[http://www.tagnice.com  nike air yeezy shoes]

 However, when I turn on the audio driver in preparation for playing test
 sounds, there is a slight turn-on click. In my experience with other
 computer audio systems, eliminating such clicks often requires some
 careful software work to ensure that the DAC output is at 0V prior to
 turning on the amplifier.
