First, Thomas, I apologize for sounding irritated above, but if you saw the volume of comments I've seen addressing the wrong (external/soundcard) speaker for this problem you would likely agree.
Joseph, I changed the tag to read 'kernel-bug-exists-upstream' as the problem persists with v4.7-rc6 mainline.
