У меня проблема с изменением громкости звука приема netstream

И это не работает. Кто может мне помочь, пожалуйста? Обновление: выложил полный код. Я использую FlashDevelop 4.6.4, Flex4, SDK 4.6, flashPlayer 11.1. Я имею в виду, что если streamRcv soundTransform громкость больше 0, звук "включен", но не меняется с более сильным "rcvVolume". Если streamRcv soundTransform громкость равна 0, сначала видео не имеет звука, но если перетащить ползунок, громкость звука регулируется нормально.

Решение
На Flex для воспроизведения видеопотока мы можем использовать VideoPlayer или VideoDisplay компоненты или Video объект с NetStream,
Это минимальный рабочий пример того, как использовать эти элементы в прямом эфире и как настроить их громкость звука:
