[tlug] Flash content plays double speed

[CL <az.4tlug@example.com>]

Flash and other video content in both Kubuntu 13.04 and WIN 7 VBox 
accessed through my browser plays the files at double speed.  Fans of 
Simon, Theodore and Alvin may find this charming, but I am having a hard 
time listening to BBC, CNN and podcasts. My main browser is Firefox in 
both OSes, but the same problem also occurs in Chromium, Chrome, Rekonq, 
and, after a file has been played in my browser, Skype sounds run at 
double speed, as well.

My plugins are:

Kubuntu:
- Flash Player
- VLC Media Plugin

WIN 7 (in VBox)
- Flash Player
- VLC Web Plugin
- Shockwave for Director
- Quicktime
(and, I'm sure that Windows Media Player has it's fingers in there, 
somewhere)

I have tried rebooting and restarting all browsers in Safe Mode but 
still have the problem there, too.  I have Skype startup diverted to so 
that it does not use the Pulse Audio server (see my post of 08 JUL 13 
"Re: [tlug] Sounds of Silence - SOLVED) but, if I start Kubuntu with 
Skype not loaded, the problem persists.

Google has not been my friend, so far.  Can anyone think of another 
thing I can try to find the cause?
