On the MCB4300 the configuration is for sure different. There is an audio example for the Keil board in the LPCOpen package which you can find here:
[list] [*] Go the folder ".\lpcopen_2_12_keil_iar_keil_mcb_4357\applications\lpc18xx_43xx\keil_uvision_projects\keil_mcb_4357" and select the project "keil_mcb_4357_periph_examples.uvmpw" [*] Make a batch build (Project --> Batch Build) and download it to the board. [*] If you receive a message that one or the other file was not found you have maybe put the project too deep into your file system. In fact it needs to be quite in front, e.g. C:\NXP\LPCOpen\<here>, because the Keil environment has a problem with paths longer than 255 chararcters. [/list]
