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 helpfulIts possible that I'm missing something very simple here. Any help would be appreciated. Thanks!
I don't know the technical details of S/PDIF, so I can't say whether or not it's possible to send an AAC stream through it. But even if it is technically possible, I doubt that your equipment would be able to decode it, even if it's configured to decode AAC from discs, flash drives, or however you'd otherwise get it to your receiver. Nobody sends AAC through S/PDIF, so there's little reason for a manufacturer to implement that on their device. Why not just decode the AACs on your PC before sending them down the wire? S/PDIF is perfectly capable of handling 44 or 48 kHz decompressed audio.
i have the same problem. i've searced many sites, but couldn't find a solution. aac->ac3 loses some quality.

How would I go about doing that, though? I definitely have a multi-channel AAC video, it just downmixes it to stereo on my receiver, though. The AC3/DTS stuff gets properly represented as multi-channel modes on my receiver, on the other hand.Edit: typo.
