Unfortunately, Creative has removed the posts regarding Crystalizer on Audigy.

As far as the question regarding Audigy Dolby Digital Decoding, I believe daniel_k's drivers reenable it. But you need to have SP1 installed for it to work. The advantage here is that the integrated decoder has the ability to decode signals coming from the SPDIF-IN.

Do note however, the DSP was never used for decoding purposes! It was always done on the CPU.
