You must use a multi-channel application that supports the
WAVEFORMATEXTENSIBLE tag. 

Logic Audio e.g. supports this format via EASI-MME. However, you should
modify the number of channels manually via the registry
(HKEY_LOCAL_MACHINE\SOFTWARE\emagic\EASIMME\Drivers). This is because
KMixer reports 0xffff (!) number of channels to the MME API. 
It is a good idea to set this registry value (the actual number of
channels that Logic would use) via your driver INF file.

Hope this helps.

Best,
Carsten
