Please post log and ffdshow setting screen shots for 1) mixer screen 2) output screen 3) resampling screen. SAF might be having pretty bad settings for ffdshow. Currently I'm not recommending using SAF for testing at all.
Only if passthrough is enabled, default setting should be OK.
ONLY That will kill the audio renderer's ability to work completely (I even wonder why it was able to connect, since even that should fail for passthru formats - but I need a log to analyze that). Please have a look on the first post for more technical details.
Tourettes, durning SAF install, SAF ask user if enable audio passthrough or not.
If you click no, FFDshow setiing are fully compatible with your renderer, as i wrote, only stereo mixer is enabled. Still, ffdshow audio settings window popup durning SAF install, and you can simply disable mixer or select different audio output (5.1, 7.1, etc...).
That is all.
