I have stream from IP camera which gives RTSP, I stream it as RTMP from media server, and that works fine, but on client side in FlashPlayer when at the same time I'm using Microphone.getEnhancedMicrophone() for exmaple for publishing stream (but publish isn't needed). The receiving stream audio breaks, and a lot of cracks can be listen. Using just Microphone.getMicrophone() doesn't produce this bug. When I use getEnhancerdMicrophone() I can't just drop Microphone microphone = null or something, I have to execute Microphone.getMicrophone() and than cracks stops. I have tested on two Flash player version 11.3 and 11.5. In Chrome, IE if I make playing and getting microphone in two tabs, problems doesn't exists, but on Firefox and Opera when on any tab is getEnhancedMicrophone executed problem exist on all other tabs with stream restreamed from RTSP stream. When I'm working on regular RTMP stream everything works fine.
