I was playing recently with Ubuntu 10.10 alpha3 and Fedora 14 alpha1 and I’ve noticed a common bug: if you try to play flash video it plays very fast and usually without the sound. Sometimes when playing video I see that my web camera is turning on, thus making me to think that it is completly crazy 🙂
The most funny thing is that updating Adobe flash plugin does not help: flash video still silent and still plays very fast … The solution is simple: try to install Pulse Audio Volume Control application and mute all unused devices on a system and leave only necessary one.
Open Terminal and run the following command:
(assuming you are in Fedora):
sudo yum install libasound2-plugins “pulseaudio-*” paman padevchooser paprefs pavucontrol pavumeter
(assuming you are in Kubuntu):
sudo apt-get install libasound2-plugins “pulseaudio-*” paman padevchooser paprefs pavucontrol pavumeter
Now locate Pulse Audio Volume Control in menu or run it from Terminal:
It should show something like this:
Go to Configuration and mute all devices except the one you actually are using. In my case it is Microsoft USB Headphones, so I left this item turned On. Now, restart the Firefox and check the sound of flash and flash speed again: it should be OK.
