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
