I am not sure whether I understand Your subject, but this could solve the 
problem:
There is a driver module called "btaudio" by Gerd Knorr (who wrote the 
bttv driver, too). This module works miracles... (not on my machine ;-(

(This needs a Brooktree/Conexant BT878 compatible tv card, and a 
MSP34xx/3400 or similar decoder chip for audio, which seems NOT to be on 
every Hauppauge tv card.)

The idea is to grab the audio signal NOT by line out/cable/line in/sound 
processor, but to directly access a /dev/dsp[n] device :-) which btaudio 
registers. This device will function as a OSS DSP which can be accessed 
by sox and by mplayer/mencoder (ask for proper options, if You can't find 
them, I could have a look, but I haven't got them by heart.)

Since this data is NOT processed by the analog out of the TV card You 
should have the honour to enjoy Your digital out of Your sound card.

Sorry, if I misunderstood Your subject, or if I explained bad, let me 
know, ok? :)

Good luck, Stephen D. Leedle
