Again.
Latest updates as of today are installed, Cauldron KDE, 64-bit.
- I installed the flashplayer plugin using the rpm (script) from the cauldron repo.
- I read the related Maqueia article.
- li64alsa-plugins-pulseaudio is installed.
- other sound apps work nicely (system sounds, amarok, mplayer)
Videos show but no sound (tested with YouTube, ZDF (German TV site)).
