Another strange thing, not sure if related to the hdac-rec driver: 
 - videos from youtube dont have any sound. Flash 7, FFox 
firefox-1.5.0.4,1   Web browser based on the browser portion of Mozilla
firefox-remote-20040803 Wrapper scripts for firefox web browser
linux-flashplugin-7.0r63 The official Macromedia Flash Player for Linux Mozilla
and

Sound *does* work in other flash-powered sites :
http://www.adobe.com/products/flash/flashpro/ has a marketing video  from
adobe, and it works just fine.

FWIW, i get a completely hung FFox when using video.google.com (when trying to
watch a video), or any site that references video.google.com.
