Hi All,
I've been trying to track down an audio bug where the ATIS voice doesn't play
on my system, though all the other sounds work fine. ATIS has worked
intermittently with the new sound system in the past, and definitely worked
before then. I suspect the issue is specific to my system, as I've not seen any
other reports.
I eventually tracked down the problem with gdb to an exception being thrown in
ATCDCL/ATCmgr.cxx that was being silently swallowed. I've included a patch
below to report the exception to the log.
The reported exception message is: "Failed to load wav file: There was already
an ALC error on entry to an ALUT function
at /home/stuart/FlightGear-0.9/data/ATC/default.wav"
Unfortunately, I haven't been able to get any further diagnosing the problem.
Does anyone have any hints?
