PCM2900C USB Output Data Format

I was wondering if you could help us get some information from TI regarding one of their parts. We are working on a project using a TI PCM2900C Audio Codec and need some help parsing the digital information that comes off the chip. We have written code to interface with the chip through USB and can get the digital output, but when we parse the data and try to look at the output signal, it looks as if we are jumbling the output of the left and right audio channels. The datasheet hasn’t been much help in this regard, but do you think you could find someone at TI that could provide the detailed digital output sequence for this chip? A timing diagram of the digital output would be ideal. We suspect the data may be in a standard format for this type of audio IC, but we don’t know what that format may be or where to find the details of it. This is the last hurtle for this project before we can release a full working product, so your help and any information that you could obtain for us would be greatly appreciated.
