One of the cards using the digital audio interfaces is probably a better idea,
to avoid all the very poor USB on the RPi.
I've used the Wolfson ones and they have proved very reliable (the main issue
for me is that I can't use them directly from the GPU since I can't set them as
the default output ... but via alsa from userspace they are great). They take a
bit of setting up (a custom kernel which works fine with raspbian wheezy at
least, plus a few scripts) but then are very flexible and control-able via alsa,
including the ability to choose which audio clocks to use.
The version for the older models ...
There are also versions for the + models using the 40pin breakout.
There are also cards which have fewer in-out options but they are probably
easier to use, I have not tried them ....
I have some notes from a project here that may help setting the wolfsons up, a
bit rambling but do have some useful info ...
there is apparently a recently updated kernel for raspbian wheezy here ...
