Keep hearing white noise when a flash video is playing


Whenever a flash video is playing (ie. Youtube) then I will hear white noise in the foreground and barely hear the original audio in the background. This also happens with facebook notifications and other flash sounds. I have checked my sound card and drivers and also switched the sound card over to see if this solves the problem but it seems to just be linked with Firefox at the moment

hello, maybe it's an issue with the protected mode in the flash plugin - you could try if downgrading to flash 10.3 (which is still supported) or disabling protected mode makes a difference.

Disabling protected mode didn't help but for the meantime I downgraded to 10.3 and it has worked. I shall just wait for the next security update then do a clean upgrade
