I'm told there were, probably third party, sound cards

  I haven't.   I have a really neat Qbus card with a TMS9918 sprite-based
video chip on it, though!

Which one is that? I have a Matrox card and one of the 
VSV cards (can't remember which one)

  I don't know who made it; I will check.

  It's an amazingly simple board.   The TMS9918 is very easy to use to
begin with...All this board appears to be is the standard TMS9918 app
note circuit with some glue logic to connect it to Qbus.   It should be
trivial to bring up and get graphics out of if I can find out where its
CSR sits.
