FLV NO Sound!

Hi, i play FLV files downloaded to my PC and there is video but no sound?

I have been playing the FLV videos for weeks then all of a sudden, the sound dissapears but all other windows and

media player sounds work?

I do a fresh instal of "any flv player" and still no sound?

I do a system restore and still no sound?

I use another player ie. VLC media player and there is sno sound, but there is video image as with any flv player.

I assume it is a sound coded fault but if you reinstal player and use another player even', u would think the faulty

codec would be replaced and all would be well!

Please, any ideas,

Thanks

I had the same problem:

Only two things happened between the time FLV last worked and when I first discovered that the sound was gone on FLV player.
1. I installed Microsoft updates KB961371, KB973346, KB971633
2. I installed magic Jack on my Desktop computer

When I discovered the no sound condition on my desktop I checked my laptop - FLV player worked there.
I already have magic jack on it. But just to be sure I uninstalled Magic jack on the desktop anyway.
I also uninstalled the 3 Critical Updates listed above.
Then I noticed that emptying the recycle bin did not produce a noise either.

What fix it (for me - you may need a different solution):
Go into control panel, sounds..., Audio (Tab): Look for something like modem #0 line playback
set this back to Windows default audio or what ever used to be there.

After that, my FLV player sound and Windows sounds can back to life.
I hope this is your solution as well. Good luck.
