      Hello, I am seeing ever increasing memory consumption whenever I attach a QAudioProbe to a QMediaPlayer (which I then play) under Windows. I don't see this behavior under OSX, nor do I see it when QAudioProbe connects to a QAudioInput (as in the AudioRecorder example).

      I have tried deleteLater and delete, and then recreating the probe but this does not free up any memory. Eventually, the app consumes all the free memory on my pc before crashing. Workarounds or suggestions would be highly appreciated. Thank you.

      Update: I experimented with QAudioDecoder and found that it has the same memory leakage issue. Perhaps they are related.
