I installed from here -> because I was having so much noise from my speakers when the sound wasn't even playing, and I decided to install alsa drivers instead. Now, they are very good - but I've lost the ability to play any flash in any of my browsers.

Running ubuntu 11.10 on 64bit.

You should check if flashplugin is trying to use pulseaudio device.

Ubuntu's wiki might be useful

Yes that's right, it was pulseaudio prior to the change – Jonathan Apr 3 '12 at 19:30

sudo apt-get autoremove pulseaudio

Fixed this by making sure pulseaudio was completely removed - I had also tried to change flash, so re-installing flash might be required if anyone else has this problem.
