This is a follow-up to my previous question Proper way to include unnumbered chapters in a per chapter bibliography using biblatex.

The solution proposed by Audrey breaks when I use the titlesec package to modify the chapter headings. Here's a MWE:




\usepackage[style = phys,%
            backref = true,%
%           citereset=chapter,%


% Extend biblatex's \chapter patch to \chapter*
% Save data for bibliography titles
     Chapter~\ref{refsection:\therefsection} - \nameref{refsection:\therefsection}}}{}{}


  \section*{References for \csuse{subbib:\therefsection}}}

{\bfseries \LARGE \bfseries }{ \thechapter}{0.75em}{}[\vspace{2ex}\titlerule]

  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
  author = {Cuthor, C.},
  year = {2003},
  title = {Charlie},


\chapter{Chapter 1}




\bibbysection[heading = subbibliography]


The result in the bibliography is this:

enter image description here

As you can see the references to the chapters have disappeared. There not even any question marks. I guess this means that the \csuse{subbib:\therefsection}} portion of the solution by Audrey points towards nothing after I insert the redefinition of the chapter format using titlesec's \titleformat.

Also, putting the \titleformat{...} redefinition of the chapter headings before the biblatex patch ends in the following error argument of \csdef has an extra }.

Any ideas how to work around this?

Appending the chapter macros is likely the problem. You can move the control sequence definitions for the titles just after biblatex's prepending patch.
