I downgraded Flashplugin from (11.2.202.238-1 => 11.1.102.63-1) and the sound is now back to a good quality.
]]>Edit: Finally checked an HD video on Chromium and and the sound is distorted also, so it is definitely a flash issue.
I have decided to finally ask on the forum, I have been searching for a while and playing with Pulseaudio settings but nothing works.
As stated above, I have a distorted sound while watching flash video in Firefox but not in Chromium, and as far as I can see it use the same plug-in.
So any idea or direction would be appreciated to resolved it,
Many thanks,
