Comment 41 for bug 68187

Praveen and xcorex, are either of you still having issues after installing libflashsupport as Guillermo suggested?
The libflashsupport package Guillermo suggested sounds very promising (it provides support for PulseAudio in Adobe's Flash Player 9), but after some messing with settings to get a quasi-default Amarok install, I no longer get any errors, even with last.fm playing along in Firefox when I open Amarok up.
 I'm not sure why Guillermo suggested installing libflash-mozplugin though. It is a GNU alternative to Adobe's flash, but as far as I know, it does not work well with Flash 9 content.
