[K12OSN] The sound issue

[Peter Scheie]

Well, yes and no.  I already had Gadi's sound package installed on some 
K12LTSP 5 servers.  This (along with Gadi's and Jim McQuillan's help) 
was necessary to get sound working on a bunch of Dell laptops. But that 
was prior to the upgrade to Flash 9, and the libflashplayer.so that 
comes with Flash 9, broke flash sound, at least on my servers.  I 
neglected to say which version of K12LTSP I was running in my previous 
messages, and Eric's quick fix of running 'esddsp firefox' probably 
works for 6 but not 5.  For the record (and archive searchers including 
myself), I was able to get sound working again with Flash 9 using 
Jean-Michel Dault's Pulse Audio package at 
http://pulseaudio.revolutionlinux.com/PulseAudio.  Download the source 
file, run make and make install, just as the instructions say, and sound 
under Flash 9 works.  I installed the following before running make, but 
they're all available via yum:

openssl-devel
esound-devel
pulseaudio
pulseaudio-devel
subversion

The subversion package is needed to download the Pulse Audio source file 
from Revolution Linux.  Hopefully, this info will be useful to someone 
in the future.
