Ok, I've looked at my settings.
Note my hardware is Core i3 using HDMI for video only, optical for audio.
First off I have never adjusted anything with FFDshow itself other then stuff for subtitles. Certainly nothing for audio.
But for me getting everything setup properly for audio was in 2 parts: 1) Getting Shark setup and 2) Getting my AVR properly configured.
As for Shark I would start by using the recommended settings...this is a good base that may work "out of the box" for you. I do just some minor tweaking beyond this base. If you've been messing around in FFDshow itself you might consider uninstalling everything and then reinstalling Shark fresh.
Also remember that I have 32 bit only so unsure what you need for 64 bit but sounds like you just need to setup both to match.
Here is what I have on various tabs:
Audio tab I haven't touched the left side, leave at defaults.
Right side I have checked Use pass through for FFDshow S/PDIF and enable Audio Normalization.
MKV tab I use Gabest's splitter because Haali is buggy for me and I get better subtitles using Gabe. May help with your audio so give it a try.
Also I Disable the DivX Media Foundations.
Swap tab for AAC Audio I use FFDshow's codec. On the right side I have checked Use FFDshow for MP2/3 instead of MS and Disable Windows Media Foundation. Everything else is unchecked.
Now part 2 is your AVR. Honestly this was the bigger thing getting true passthru to work. At least on mine it wants to use various processing and "sound fields" which I don't want. Took me about 10 minutes going thru my manual (most of that actually trying to find the manual) until I figured out how to turn all that crud off so now when DD 5.1 or DTS hit my AVR the display just says "Dolby Digital" or "DTS" instead of some sound field like "Movie" or "Action". Thus I am just getting the pure sound thru. Now for 2 channel stereo I do have it process it to Dolby Prologic II, but that's pretty common.
You may also have additional settings in the AVR for how it handles HDMI audio too. You could try using optical for audio instead and see if that solves the issue.
Hope this helps.
