Hi Dominic,

if you compare figure 37 and 39 you'll see the difference. I've soldered the two
resistors 27k and 13k and the diode D1 directly onto the IC1 (these 4 devices
are SMD parts - I had to use a magnifying glass an a very fine pitch soldering
iron) and made connections to pin 3, 10, 11 and 28 of pcm2902. This "piece of
crap" is fixed with hot glue and I'm done.
You can substitute the voltage regulator by any other low drop type - the
enable input isn't imperative. The pcm2902 codec needs about 3.6..4.0 volts at
pin 10 to override it's internal voltage source.
Good luck.

Ciao Martin
