Mmm, it seems the Turtle Beach Montego, HiTeC Digital Audio (HDA) 
X-Mystique and Diamond Xtreme Sound with DDL all have the same chip-set, 
the C-Media CMI8768+, (note the +, that is what signifies the DDL 
encoder) the Diamond card is the cheapest, this is probably at the 
expense of the analogue circuitry, which, if your using DDL, is irrelevant.

Unfortunately it appears the DDL feature is *NOT* supported under linux

bottom of page 6 bugger.

In other news HDA now make card that supports not only DDL but DTS 
Connect (the DTS equivalent of DDL) that is apparently built around a 
custom chip-set, the C-Media CMI8770, so I'll be emailing HDA requesting 
information on Linux support for this feature, can I urge others to do 
the same and post any useful responses here?
