Playback AAC HE 6 channels

[viz]

With different configurations of ac3filter, coreAAC, FFDshow audio and so on I can send without problems an AAC LC encoded audio-stream directly to the SPDIF output of my pc. So far, so good.... 8)
Though, I still have troubles in doing the same with AAC HE encoded audio. Either I get only two channels, or I get a "noised" output. :roll:

Any ideas?

Thx
