Thanks again.

To make the breakout board easier to use with a PC for s/w development, today I moved the honkin 470uF capacitor (C16) to a better location on the board, so that it doesn't totally block the analog audio-in jack. Duh. WTF lays out a board that poorly??

Then I found a relatively slim profile 1/8" audio cable and trimmed enough vinyl from the side of one connector end so that it can actually mate with the zero clearance jack on the board. Another major design fail that!

Cheers
