The TrueHD fix is contained within the latest beta release, if the latest beta does not work then the problem does not lie with the recent TrueHD changes and is something else.
The build I shared previously on this thread includes a new demuxer which will be released in v9.1. I’ve created a new build that uses the new demuxer, from the sounds of things this should solve the issue if your still having TrueHD files getting stuck loading.
