Flash plugin in firefox without sound

My firefox can play videos but has no sound there.
After upgrading firefox I cant hear sound in flash videos like youtube. I have tryed deleting and reinstalling firefox, flash-player, libflashsupport etc.
I have seen this problem everywhere but I have no real solution for this. Any other suse user has this problem fixed?


My defaults:

Opensuse 11 + gnome + alsa sound

Please help !!
