I have a similar problem on my Windows 98 computer - more specifically, the
first time I play a .flv the sound works but afterwords I will not hear any
sounds from my .flv's;

on my Windows XP I do not have this problem;

I've got Win2000.
As I have noticed, when I'm clicking right button on flash movie, and choosing
there microphone, microphone sensitivity progress bar DOESN'T move ANY MORE
(before it was moving)! But microphone is on, and I can even hear myself in
speakers!

Hi!
All my FCS application now are not streaming sound! I don't know why that can
be! Maybe, becouse I've installed second USB webcamera+microphone? I don't
know, but now even FCS samples are not streaming sound!!! What can be wrong???
