[P35-DS3R, Realtek ALC889A, Green Line Out, Rear] Sound is distorted in some Flash videos

[pschonmann]

Hi, i have problem with sound from some flash videos.
For example - http://www.htfr.com/product.php?productID=104984
Sounds is little bit digitized. I dont know its bug from flash, jwplayer ( video from jwplayer homepage plays well ) or just something with pulseaudio.

Feel free to change package, because i dont know how to report it in better way than ubuntu-bug audio. And of course feel free ask to me for details.
