Audio issues since Chrome OS updates

Like many people around the world, I have been glued to the Al Jazeera coverage of the popular uprising in Egypt, which really highlighted a problem that started to occur after the Chrome OS update I posted about last month.  After the update, the audio in audio or video feeds would suddenly turn into a mix of static and squealing. The only way to fix it was to restart the Cr-48.  But, it looks like the last update that just loaded last week may have fixed it - here's hoping!
