This is my first direct bug report, so I apologize in advance if I am not following all the bug reporting etiquette.
The above bug manifests itself in visual studio 2022 on windows 11 as:
qt.multimedia.audiooutput: Failed to setup resampler
I eventually tracked the issue down to a initialization order deep within the QT multimedia framework. I created a qt desktop forum post describing this issue but I did not get a follow up (admittedly the post was not too clear).
My project uses the 'Active Object' approach to delegating all my audio processing to a dedicated worker thread. I attach the source and header for this RtpWorker class.
It works fine with the workaround preprocessor directives in place
#if defined (RESAMPLER_BUG_FIXED) is obviously not defined here.
