Hi Devendra In our driver we supported 32bit->24bitMSB format first, but then found that some application (like wavelab,...) can't record 24bit in this format. So we added support for 24bit packed. After some testing we came to the conclusion that if you want to support all programs there is no other way than to support both types.
