No stupid question. 
Yes, that's to output the clean DD/DTS signal to my 6.1 sound system receiver. Just enter ffdshow's audio configuration (windows start menu) and set "AC3" and "DTS" to "S/PDIF" (see appended screenshot). This way AC3 and DTS are not converted to PCM by the computer, but processed by the receiver. Best quality you can get for digital audio.
All other settings must not be touched, depends on what audio codecs you wanna have processed by ffdshow, of course. The appended screenshot is just a sample.
