GPIO is a bit limited on the RasPi.  If you want decent audio out of the 
2835 directly (rather than via USB) then a better option would be to 
hook up an audio codec to the I2S lines and enable the driver -- I think 
this is available for the RasPi, but you'd need to check with the 

I believe I can say that I have quite a good grasp of what the 2835 is 
capable of.
