The Hauppauge WinTV Go card normally comes packaged with a short audio 
jumper cable, and printed instructions about how to use it to connect the 
card's audio out to line-in on a sound card. Because this information is 
pretty clear in the how-to-install docs that come with the card, I suppose 
nobody thinks it needs special explanation in a Myth context.

Back when I was an active user of MythTV, I wrote some introductory docs 
that mentioned the fact that bttv-based cards often do not support btaudio. 
I think they are only to be found in the archives, though, much as you did 
(in fact, I believe the item you quote above is from one of my drafts).

In practice, use of btaudio is the exception ... the normal way to do the 
audio portion of vidcap in Linux (and in Windows, for that matter) is via a 
jumper cable to the sound card ... this is true of just about any vidcap 
software, not just MythTV. The draft you seem to have found should discuss 
other cards, including mention of the ones that are reported to work with
