No 5.1 surround sound (he-aac with html5)
We produced 5.1 he-aac files http://www.kulturradio.de/_testfolder_fuer_alle/5-1.html
In Firefox only a stereo-downmix is to carry. IE, Chrome and Safari on Mac do the right - transfering the 5.1 signal to the sound card.
Any Ideas? Is this a known FF bug?
I currently use FF 33 but has never really performed at pevious versions.
Thanks for your help Sebastian

It seems to work but the sound is awfull at my notebook. It sounds blurred. Maybe the decoder is 5.1 but buggy now?
Hi Sebastian_Fisahn, There was a new Web Audio too that was added to the Web Console in this new version. But the website you are referring to is using JW player.
I also tried to research the JW support and it seems it only on Windows? http://support.jwplayer.com/customer/.../search?q=surround+sound+firefox
IF you download the audio and play it on a local computer, does the sound quality change?
I do not know if this is a current bug, there is no harm in filling one however.
Please see [bugzilla.mozilla.com] and their link for how to file a good first bug.
I played our native channel-test-file via download here: http://www.kulturradio.de/programm/feature/5punkt1/willkommen.html
The new audio-console is "Waiting for an audio-context to be created".
I'm afraid FF don't like he-aac covered in mp4??
Then I have tested with "aac" or "m4a" file-endings also with no success. http://media.rbb-online.de/kul/test/gut_aac_multichannel-5_1.m4a http://media.rbb-online.de/kul/test/gut_aac_multichannel-5_1.aac
Sebastian, I am seeing the same in the audio console. I will follow up on this. See https://bugzilla.mozilla.org/show_bug.cgi?id=1074308 may need to investigate this more.
For the he-acc, this may be related https://bugzilla.mozilla.org/show_bug.cgi?id=875644
It does look like it is an issue in FF, and the bugs will be able to further investigate a fix. In the meantime, however are there other formats of the audio that could be offered for Firefox users?
I also tested 5.1 ogg/vorbis without any success. I'm sure that i googled, thats a already known FF bug.
I believe I have misinterpreted the expected behavior of the Web Audio console.
