I would also really like it for FlightGear, and I know sufficient CoreAudio to say, the work is not very difficult, but I didn’t find a spare weekend so far to contribute a patch. But I think it’s only a few hours work, the CoreAudio API is not so complex.</div><div class=""><br class=""></div><div class="">I would really recommend fixing this in the OpenAL code BTW, manipulating audio-units directly gets more complex fast, is my limited experience.
