Is there a reason that --disable-sound doesn't totally disable sound?
Is there a way to totally disable sound? --help --verbose doesn't give
any further clue that I noticed.
I am still having major problems getting FG to work with pulseaudio (and
I don't want to (nor really can) kill off pulseaudio).
In summary:
Sometimes everything is perfect with the c172, sometimes it hangs
before the splash screen goes away, there is no rhyme nor reason, I
suspect there is a race condition of some description.
I don't think I've successfully got any other aircraft to work, they
always hang before the splash goes away, again probably a race condition
I suspect which other aircraft trigger more readily than the 172.
Even with --disable-sound, we get the same hang, the backtrace of
which follows, so I can't even fly soundless :-(
Talk about frustrating, havn't been able to FG properly in ages,
withdrawl symptoms!
Here is a --disable-sound backtrace which shoes that it's still trying
to use openal (and thus pulseaudio) even with no sound.
