Summary: Audigy 2 ZS Platinum's hardware AC3/DD decoder isn't
supported?
Description:
If I have understood right this card should be able to decode AC3/DD by
itself when sent into SPDIF/IN...
Well Sending AC3/DD signal to card's SPDIF/IN results in crackling noise
from my 7.1 analog speakers that are connected to card. Sending PCM into
SPDIF/IN works fine, but it would be nice to get AC3 (and by that way DD
sounds) alive and kicking.
Am I doing something wrong or is it just that emu10k1 doesn't support
Audigy2ZS's hardware AC3 decoder? If so please tell me what I am
doing/have understood wrong or are there any plans to get hardware AC3
decoder to work?

These devices have no hardware AC3 decoder - Creative is lying. It's
implemented in software in the Windows driver.

Hardware has no AC3 decoder. You can do it in software by piping the input
to ac3dec.
