Firefox audio problem with flash plugin

[C. Jeffery Small]

Xeon E5 64 bit system
Xubuntu 14.04.1
Firefox 32.0+build1-0ubuntu0.14.04.1
flashplugin-installer 11.2.202.400ubuntu0.14.04.1

Audio plays properly on this system through all media players as well as the Chrome and Opera browsers. However, no sound was issuing from the Firefox 31 or 32 browsrs regardless of what video or audio source was selected. After considerable work and a joint investigation with a Mozilla developer:

see: https://bugzilla.mozilla.org/show_bug.cgi?id=1062556

it was determined that the proble was with the Shockwave Flash plugin. When this plugin was disabled, sources such as youtube would see that flash support was unavailable and resort to HTML5 which plays audio just fine. However, disabling the flash plugin means that all flash content is unavailable -- both video and audio.

This plugin interface needs to be investigated and repaired so that audio support can be restored.

Somehow this got tagged for the mdadm package although I know that I set it properly. I'm updating the target package to the flash plugin.

I hope someone will review this and treat it as a serious bug!

Here is some additional information relating to this issue.

As best as I can tell, the Opera browser (ver. 12.16) is using the same plugins as Firefox (32). When I visit the following page:

http://flash.flowplayer.org/plugins/flash/content.html

Opera produces audio output with this video while Firefox does not. Opera also seems to properly produce audio in flash youtube videos in flash mode while Firefox cannot -- although if the FF flash plugin is disabled, youtube videos will fall over to HTML5 mode and then audio is produced. Chromium works well in all situations with it's own Flash 11.2.r999 plugin.

The following site:

http://www.radioio.com/channels/jazz/real-jazz/play/?play

is a streaming radio channel that has worked well in the past. It currently plays with Firefox 31 on my Solaris system and Firefox 32 on Windows XP. It also plays fine using the Ubuntu Chromium browser. However, it fails to load (i.e. connect) to the stream on both Firefox and Opera. I include this in the hope that it offers additional clues as to what is wrong here.
