AVDD17 or 27?  I think 17 is the line out and mixer, 27 is the headphone.

For both.

AVDD17 derived from AVDD27.

If someone interesting: SD card 32GB class 10 eat 0.6mA  :)

I tested battery life on some builds:

Last spring: 10h 14min
Current git: 13h 35min
Current git + 1.1v CPU (no change to other clocks): 15h 0min

Thanks;
is that so special to the Clip Zip, or is it easy to adapt to other Sansa devices?
