Re: [97attendees] Thanks for Seoul (Re: Food poisoning)

Hi Brian,

thanks for your feedback.

We installed FlashBlock and managed to reproduce your issue. It seems 
that FlashBlock blocks HTML5 <audio> and <video> elements, even though 
they have nothing to do with Flash. While <video> elements are replaced 
by a custom button you can press to un-block them, <audio> elements are 
not visible by themselves, so there's no action you can take to let 
sound flow correctly.

Also the self-test application gets stuck and hangs for the same reason. 
We'll try to add a further check to detect this particular condition in 
the next version.

Best,
the Meetecho team
