why do youtubes play at double speed?

[Robert P. J. Day]

  i've been fighting with this for a while -- any attempt to play
youtube videos plays them at what appears to be double speed, no
audio, and fairly erratically.  i have a fully-updated f11 system, and
i have no idea what the problem is -- flash had been working fine for
the longest time.  any thoughts?
