Update on symptoms: I went back to osg-2.8.2, updated SimGear, fgfs, and data from cvs. Recall that I upgraded from FC10 to FC12 using preupgrade. Sound is fine in several other applications. My first run of fgfs had no sound and great frame rates (throttled to 30) at KHAF and KSFO. When I used file > Quit > Exit to try and end fgfs, it locks up completely. If I minimize the window and then maximize the window, it is black. I then used Applications > System Tools > System Monitor to kill the fgfs process. fgfs process is using 100% of cpu before I kill it. When I restart fgfs, it has very poor frame rate and crackly sound. If I kill the pulseaudio process, and then run fgfs, pulseaudio process is back, I am back to no sound and great frame rates and when I exit fgfs, it locks up again.
Anyone successfully using fgfs with sound in FC12? Dave P.
