I'm having this problem now with firefox-esr-24.1.0,1, but actually it was the same with Firefox ESR 17. I can watch HTML5 videos on sites like YouTube or Vimeo, but there is no sound.
I have Firefox built with the GSTREAMER and ALSA options. Checking http://html5test.com shows in the "Audio" section that all audio formats (PCM, AAC, MP3, Ogg Vorbis, Ogg Opus, WebM) are supported.
GStreamer can play MP3 and AAC files from the command line:
Any ideas on how to troubleshoot this further?
Regarding sound in HTML5 video, which of the Firefox port options is actually significant, GSTREAMER or ALSA? It seems logical that Firefox directs all multimedia, including sound, to the underlying GStreamer which then uses ALSA, PulseAudio or whatever else to actually play the sound. So why the extra choice between ALSA or PULSEAUDIO when building Firefox?
