Yeah, good luck with this one. People always talk about the multiple timelines of the Eighth Doctor, but really, the Seventh Doctor is just as bad — or worse. The reason is really Ace. Because her timeline is so confused, so, too, is the Seventh Doctor.
I don't think that it's possible to really nail down the audio stuff — especially given the fact that Big Finish have directly said that anything with Raine Creevey is an an alternate reality to their own output. (Yeah, thanks for that, Briggs.) This compromises Ace even more and therefore, the Seventh Doctor.
Additionally the early, pre-Ace solo DWM stuff is a bit crazy to figure out, as is the solo IHP stuff. There's no particular reason to put the IHP stuff in publication order, as there's not much of a narrative imperative to do so. The Death's Head story has to come after the Death's Head meeting in DWM, of course, but that still says nothing about the placement of that story relative to all the other IHP stories
The truth is, there are tons of gaps where you can fit audio solo adventures. Too many. Way too many. You can pick from any gap between two solo comic stories, multiple points within individual NA novels where the Doctor is separated from others, or the vast, undefined space pre-TVM. The audios tend to, but do not always, feature TARDIS sounds which are taken from the TVM. So most of the solo audios seem to be in that later gap. Where the solo adventures are relative to each other, though, is usually pure guesswork.
