Yep - same question...
I've got everything "working" but there is a whole lot of white noise over top of the music. Going to verify the direction of the tantalum caps mentioned above but also just curious as to what values people are using for - here's what I have currently.
R4, R5 - 10k
RR6, R7 - 10.0
C14, 15 - 150uF (partls list has 33uF for these - that's what I'll try next)
C36, C40 - 150uF (parts list doesn't have these - maybe they shouldn't be stuffed? - not sure how that will affect attenuation...)
after this I'll try the values shown in the CS4340 datasheet

I posted this when I finished my first minty:
The sound I'm getting out is pretty bass heavy (not distorted though), the highs are not very present if at all. I'm using:
C14, C15, C36, C40 = 33uF
R4, R5 = 10 KOhm
R6, R7 = 10 Ohm
(i think the minty #2 I've been trying to build has given up the ghost. the board is pretty trashed at this point, and the FTDI chip and/or the PIC might be toast as well.)
