How do I fix Flash issues?
I use Kubuntu 12.04 LTS, and in Firefox and Chromium the Adobe Flash plugin will not play audio.
Google Chrome's plugin works, but I don't really like Chrome/Chromium, I installed Chromium only to test it.
I tried various versions of the plugin and both adoble-flashplayer and flashplugin-installer. Tried the "delete .pulse and create some files" fix and didn't worked too. Tried every single fixd I found in web and nope, didn't work.
