So far, I have been able to work around any little gotchas on Ubuntu pretty quickly. That said, I am currently dealing with trying to get the Flash Player to play sound under Ubuntu. I am not having problems with system sounds, RhythmBox, Totem, etc. But, for some reason, about 90% of the things I try to access Flash Player with don’t produce sound. I have found quite a few postings on this problem but haven’t found a working answer yet. I will post what I find works for me!
