Ok, I did as you said and used the Py::ExtensionObject, however I seem to be back where I started with object not being deleted :(

The problem seems to be that somehow it thinks it still refrenced when its not, that is when I checked the refrence count before destroying what should be the final refrence it reports a count of 2. Whats more when the object is first created the count seems to start at 2...

Where the object is created
    //create voice object
    Py::ExtensionObject<SourceVoice> voice(new SourceVoice(sourceVoice, Py::ExtensionObject<Sound>(this), loop));
    std::cout << voice.reference_count() << " ";//2???
    audio->extensionObject()->AddSourceVoice(voice);//the Audio class maintains a reference (basicly adds to playing set in Audio class)
    //start playback

    std::cout << voice.reference_count() << std::endl;//3, as exspected since refrence was 2 before
    return voice;//in my tests this return value was not used

The objects constructor - I see nothing here to create a 2nd refrence to itself, only an extra refrence to the Sound object
SourceVoice::SourceVoice(IXAudio2SourceVoice *_voice, Py::ExtensionObject<Sound> _sound, bool _isLooping)
:voice(_voice), isLooping(_isLooping), isPaused(false), sound(_sound)

Where the final refrence counts should be removed:
    for(std::set<Py::ExtensionObject<SourceVoice>>::iterator it=playing->begin();it!=playing->end();++it)
        if(state.BuffersQueued <= 0)//finished, we can clear this up
            //since erasing invalidates the iterator, we add it to a seperate container to delete later, safly
    //clear up finished sounds
    for(std::vector<Py::ExtensionObject<SourceVoice>>::iterator it=finished->begin();it!=finished->end();++it)
    //here the last refrence should be deleted, since the python test code never kept the refrence returned before
    //and nethier the playing or finsihed list now have a refrence to the SourceVoice object
