Created attachment 712086 [details] firefox_audio_issue.html User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130201065344 Steps to reproduce: I retrieved a local media stream via mozGetUserMedia and assigned it to a video element (see attached code). This is in Firefox Nightly 21.0a1 (2013-02-08). Actual results: Talking into the mic without headphones results in really bad echo. The echo feeds back into itself and gets louder. An interesting secondary effect is that, after triggering this bug, I then get the same echo in Chrome when using getUserMedia. Restarting Chrome fixes this, and I can't repo it in Chrome without first triggering it in Firefox. Expected results: No echo

Unlike Chrome, Firefox does not auto-mute audio when a LocalMediaStream is assigned to a audio or video element. Just set muted on the video element. We do not currently support AEC in pure getusermedia loopback cases, only across peerconnections where there is real remote audio being played.
