[Plib-users] slScheduler: Too many pending callback events!

[Per L. <li...@ho...>]

I can't run any program that uses SL! FlightGear doesn't run at all if I don't
specify --disable-sound, TORCS does not run and gives the error message

slScheduler: Too many pending callback events!

and I get the same error message when running the SL/example program. I *can*
run mod_demo without problems.

I use SuSE 6.3 on a P3-500 and own a SB Live 1024 (I use the drivers shipped
with the SuSE distribution).

Any ideas that might help?

Regards,
Per Liedman

This is *very* strange...I've never heard anything like this before.

* Does the mod_demo program actually play music?

* Do the other programs make any sounds at all before they die?

* What window manager do you run?  Does it have it's own sound
  manager like 'Enlightenment's  'ESD'?

* Were there any other messages on startup?  Any warnings from
  the compiler?

What's odd about this is that 'flushCallBacks' is called every iteration
in the 'slScheduler::update' function - and flushCallBacks *MUST*
empty the 'pending_callback' list unless the sound device is
notWorking().  However, if the sound card isn't working then 'addCallback'
can't run either and callbacks can't be added to the list - and the
error message cannot appear.

I'm utterly mystified.

I had the same problem, but it's easily fixed. Look in example.cxx
around line 50 or so. It's trying to load /u/steve/fhead.wav, and
loading wheeee.ub is commented out.

Oops!  I hacked it around to try something - and then forgot to
un-hack it before I updated the release!

I find it hard to believe that would have caused all those weird
symptoms though.  Apart from anything else, FGFS and Torcs don't
work either.

Oh. I don't know about flightgear or Torcs. I've tried Torcs and it
works fine. Haven't tried flightgear.

Yep - flightgear is a pretty chunky download for "just a test"!
(It's a cool program though - if you like flightsims, it's worth
the wait).

Yes, this fixed the example program...thanks.

Upgrading the SB Live module also gives me sound in FG and Torcs. I guess the
drivers shipped with SuSE 6.3 were just too old.

Yes, loud and clear.

Ok, they don't actually die. "sl/example" runs until I hit ctrl-c, and
outputs hundreds of this error, but no sound is played. FlightGear plays
the engine sound, but nothing else happens (no graphics is shown after
the splash screen), disabling sound makes it run as usual. TORCS plays
something, but also locks up, giving lots of errors.

When you mention it...I use KDE, and I remember reading in the glTron
FAQ that there could be some kind of problem with KDE and glTron's sound
- but I get sound in glTron.

I will try recompiling sl and see if there were any warnings.

Lets blame KDE for now... ;-)

I don't understand, TORCS uses only .wav files.

I use KDE 1.1.2 without problems.
I was so confident with PLIB that I didn't even code a -nosound option.
I have tried TORCS on a system without soundcard and I did not get
any error message, and the program worked perfectly.

I hope that is not the SB live 1024, because I was thinking of an 
upgrade of my old SB 16...

Eric.

Yep - a bug in that one example program doesn't explain why both
Torcs and FGFS would foul up.

Ditto.

Dunno - I've been very pleased with my Ensoniq - but then I don't
need a lot of fancy stuff.
