@neuromusic can you post a stack trace for one of your errors? I think I'm just going to suppress the exceptions because garbage collecting should deal with it automatically I think

Next time I get one I will

so different spot in pyoperant, but stilli in the same spot in _stop_wav

I think I'm going to try just suppressing the exception... I'll add a logger and warning though
