Some Flash sites do not work well on my computer (Ubuntu 9.10).

Example: - can't hear sounds. - I see only the first second of each movie and then it freezes.

What am I missing?

Here is the output of dpkg -l | grep flash:

ii  flashplugin-installer                         Adobe Flash Player plugin installer
ii  flashplugin-nonfree-extrasound       0.0.svn2431-3                              Adobe Flash Player platform support library

what flash package(s) did you install? run dpkg -l | grep flash and add this info to your post, please. – quack quixote Feb 3 '10 at 22:39
Video driver? Also: sudo apt-get install libflashsupport – Shiki Apr 5 '10 at 9:43
What is the correct source to take it from? – Itay Moav -Malimovka Apr 6 '10 at 13:46

If you're getting desperate you can try to download the latest Flash plugin from Adobe itself and installing it in /usr/lib/firefox/plugins/.
