AAC passthrough (S/PDIF) solution? (PC to Home Audio) Options

[DOHCtah]

Hi guys,

I've been looking for a solution to output AAC on my PC through S/PDIF to my home audio system. My home audio receiver is capable of independently decoding AAC.

On my computer, I'm using ffdshow. It has options to passthrough AC3 and DTS, but not AAC. If I chose to disable AAC on ffdshow codecs, it still won't work.

I also know of the "convert AAC-to-AC3 on the fly" method, but I really would like to figure out a direct native passthrough to preserve quality.
I've also given thought to switching over to AC3Filter and others, but it doesn't seem like they support it either. If anyone could recommend one that works, it would be helpful

Its possible that I'm missing something very simple here. Any help would be appreciated. Thanks!

Well 3 years later I still don't know if it's possible with any software, but I have never had the need to. I think the easiest way to do it is by doing the on-the-fly conversion to DD. ffdshow can do it (you can even use another decoder if you wish, then use ffdshow's audio processor AFAIK), or ReClock can also do it. If your PC has a Dolby Digital Live or a DTS Connect card, it can also be done at the driver level. These schemes were created specifically for this purpose, to get any multichannel stream through SPDIF, but in the case of lossy multichannel you'll be doing a lossy->lossy conversion.
