AC3 over SPDIF directly to file

[Spc01]

I am having fun with GraphEdit and X-Fi Elite PRO.
I want to route AC3 over SPDIF directly via intervideo audio decoder and then to wavedest and to 6 channel wave file.

I have the folowing scenario:
ASTRA > DVB Receiver > AC3 over SPDIF (5.1) > X-Fi Elite Pro SPDIF IN.

I managed to record a file directly from line in to 2 channel wave:

Or route Line in to Wave out:

But for AC3 i'll need an AC3 Source reader because intervideo audio decoder doesn't want to connect with capture pin out.
:cool:

*By default soundblaster is routing 5.1 AC3 over SPDIF to Multi-Wave Channel out.

Any suggestions ?
