Noise, or silence on startup of ADAU1701 board.

I've made a board using the ADAU1701 dsp, but am having some strange problems when it starts.  I'm loading it via a microcontroller, and it starts up, and does the I2C transfer just fine, but sometimes it gives no sound, or just loud static, or it will work normally, but only on the first channel.

 

Any thoughts what could be causing this?
