Hi Jürgen, it is possible that TeX4ht files in Miktex are too old. Alphabetic style works for me correctly, with one small issue, the links from citations to the bibliography don't work. A BibLaTeX update could cause it, because I think links used to work.
I also found that the multibib issue that I experienced was caused by naming one of the bibliographies as a "book". Multibib then loads a file named book.aux in the way, which causes TeX4ht to load configurations for the Book class. As I was using the Article class, this fact caused a clash. When I renamed the bibliography to a different name, the file compiled without errors.
