Hi Gary,

Are you using headphone or line-out?
My i.MX6 boards all suffer from this annoying pop - it would be great
to get to the bottom of this.
Before applying my ugly fix, I can hear the glitch on both outputs,
but need to warn you that my headphones test is flawed, as the
SGTL5000 codec on my board is improperly
connected to the headphones (audio output is only 2-wire DC-decoupled
instead of using 3-wire cap-less output with virtual ground).
Are you looking for a fix for line-out, headphones, both? Also, which
kernel are you using?
Currently, only headphones.
I'm using linux-boundary/3.10.31
Which has the SMALL_POP fix applied:

Yes, but I still get them, so it's not 100% correct :-(
Also, Eric, is there anything magic about sound on the SabreLite? I know
I've had it working in the past, but today it's totally silent.
