Ubuntu – Firefox/Rekonq cannot load audio on soundcloud and bandcamp

flashsound

I run kubuntu 14.04 and cannot listen to audio files from soundcloud or bandcamp. f.ex grooveshark or youtube work just fine. I already installed the newest version of flashplugin-installer.

When I want to start a song, it seems to load, but then shuffles through the playlist without playing anything. With Rekonq its the same.

I also removed gnash, since this was mentioned to interfere.

Anybody having the same issues? Any ideas?
