Hello.
This is a known issue for H264 + AAC RTSP streams, if audio track contains type 0 AAC frames only, they all will be dropped. To play a problem stream via WebRTC you have to update to build 5.1.3641 and set the following parameter in WCS_HOME/conf/flashphoner.properties file
Code:
disable_drop_aac_frame=true
