Flash 9 Sound under K12LTSP 5

From K12LTSP Wiki

In K12LTSP version 5, yum automatically upgrades the Flash plugin to version 9, which is arguably a good thing--except that it breaks sound under Flash. (This may or may not be the case with later versions of K12LTSP.) Sound in Flash can be restored using the steps below. You may need to have Gideon Romm's OSS-ALSA sound package installed for this to work. You need to be root for these steps. You should be able to just copy & paste the commands shown below.

1. Using yum, install the following packages: openssl-devel, esound-devel, pulseaudio, pulseaudio-devel, subversion

 yum install openssl-devel esound-devel pulseaudio pulseaudio-devel subversion




2. Use the Subversion client, which you just installed, to download the Pulse Audio package from Revolution Linux.

 svn co https://svn.revolutionlinux.com/MILLE/XTERM/trunk/libflashsupport/src/




3. You'll end up with a directory called src/ in the current directory. As root, cd into the src/ directory and type 'make' and 'make install'. This will compile and install the libflashplayer.so library in /usr/lib, where the Flash Player expects it.

 cd src/ 
 make
 make install




4. Restart your browser, and Flash sound should now work.
