Wiretap Server and Wiretap Gateway now use 24-Bit MSB padding, rather than 24-Bit LSB padding for audio. Third-party Wiretap Client applications that assume LSB padding for 24-bit audio will therefore not be able to read clips with 24-bit audio from version 2011 of Creative Finishing applications. Until your third-party Wiretap client application is updated to use the new method, you can work around this issue by performing a mix-down in the Creative Finishing application.
