I built freeorion from the 0.4.4.1.1 release using osc. I immediately got a segmentation fault when I started freeorion. I opened pavu-control and turned off my 7.1 surround sound leaving only the headset and the game started up nicely. I have seen this problem with other games as well. It seems to be some module expecting 6 output channels to be the maximum but still uses the number of channels from the system which is 8 in this case.
Workaround:
Start a terminal and execute the following:
Go to the tab configuration in pavucontrol and put the 7.1 profiles to off (can probably also use any profile less than 7.1)# install pavucontrol
sudo yum install pavucontrol
# run pavucontrol
pavucontrol
start the game and enjoy
