I'm trying to transcode some lossless 5.1 flac samples to stereo using Cyberlink's Dolby Headphone filter in GraphEdit.

I've installed MadFlac, LAV Filters, and ffdshow. When I open a 5.1 flac file in graphedit I get:

and it plays back fine.

However I need to send the Flac audio through ffdshow to remap channels, then through the Cyberlink Audio Decoder, then to WavDest. But when I try to send the flac file to ffdshow it gives an error:

I've tried a bunch of different combinations of filters and in different orders... all with no luck. I don't understand why the file plays fine but is unable to connect with ffdshow. Anyone have any ideas on the correct order of filters, or if I need to install anything else (like maybe reclock?) I must admit I don't understand where all the filters/splitters/decoders exactly fit in.

edit: I've also tried the "madFlac source" filter and tried pointing that to ffdshow or the madflac decoder... still no luck.

Did you activate the "uncompressed" "codec" in the ffdshow audio configuration?

I had not - and it looks like that fixed it. Thanks for the quick and easy solution sneaker :D

edit: which is the ideal setting here? I set it to "all supported" and it added 2 ffdshows and 2 nero audio decoders in my GraphEdit chain now.

"all supported" is OK, maybe for flac input is enough "all integer"

Nero decoder?
Check if you have the ffdshow output to AC3 (encode mode)

After removing ffdshow and installing the latest version again, and rebuilding my presets, the nero decoder is now gone. So I assume something was set to ac3 somewhere.

Now I just have Source FLAC > ffdshow > Default Direct Sound Device.
