no audio out

hello, I managed to get the serial to pc connection working, and I finished assembling the minty. The MCU can read my CF card, can format, write, and delete files. it recognizes the STA013 and loads the config. However, when it goes to play a file, there is no output on the headphones and I don't register any voltage on the caps for the headphones. I'm using a CS4334 w/ 8 pins; I placed it on pins 2-5 and 12-15- I believe that's right. But there's no output! so, if anyone else who has used this chip can help me- are there any extra steps, or do I need to change the configuration for the MCU and/or STA013?

I've checked it a million times over, although admittedly the CF slot makes it hard to probe the DAC and STA013. I get the feeling the problem is either between the STA and the DAC or the DAC itself
