@Brent - Before I dive into this, is this the exact same cab you used to use on the MR1 build? I know it "shouldn't" matter but...

Also, I know it may not be your style, but did you try the three cabs I posted in the other thread? Just to see if they worked? If so and they did then it gives us (me) a frame of reference outside of my phone (single points of reference suck out loud, in Dolby Surround Sound). The three cabs I posted, at least for me, replace everything including the bluetooth, sound and battery.

Again, just getting my ducks in a row before I dive in.
