Things bode well. My, er, my friend's, values are different than yours, but I'm getting voltages in the 1v-2v range on the SCK, WS and SDIN pins, and those voltages change depending on whether the empeg is paused or playing. The SDIN pin fluctuates on voltage as it's playing and is pretty steady when it's paused. It's a low voltage in the range of 1.4v when paused, and closer to 2v when it's playing. I think that tells me the empeg might be fine, and all my, er, my friend's, problems are entirely on the bluetooth chip.
