Bug 546473

I have same problem. Game segfaulted. When I run warzone2100 with --nosound, game run. I think that there are problem with audio.

I tried another test. I run warzone2100 under root, game not crashed and run with sound.

Some messages on terminal:

[root@hunterz hunterz]# warzone2100 --window --sound

Yup, the same for me. It seems to be related to my bug #546474. I'm uncertain, if it's alsa, pulseaudio or openal-soft bug.

I think openal have problem, try openal-info under user and under root.

Even with the latest version of openal-info from the testing repo, warzone still segfaults.

Although onpenal-info functions without segfaulting. I'm guessing the bug is in pulse.

Solved for me in warzone2100-2.3-0.1.beta6.fc12.x86_64.

Setting:

drivers = pulse

in .alsoftrc fixes this problem for me, along with cracking audio I had in another (self-compiled) OpenAL game.  AFAICT this makes OpenAL use Pulse directly, instead of Pulse's Alsa emulation.  Whatever the problem is with ALSA is probably a bug somewhere but  am curious as to why OpenAL doesn't use the pulse driver by default?

In the interest of credit where credit's due, I actually found this tip here: http://wiki.archlinux.org/index.php/PulseAudio#Configuration_of_OpenAL_for_PulseAudio

The drivers=pulse fix solved my problem.

Thanks!

This bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=555112
includes a link to an OpenAL update that makes OpenAL use PulseAudio by default, so that you don't have to set drivers=pulse anywhere.  I've confirmed it works for me and the Warzone crash goes away.  Thanks to Thomas Kowaliczek for a super-quick response in packaging an updated OpenAL!

Even if that resolves the problem for users it's only because the ALSA emulation is no longer being used.  I suspect that an underlying bug exists, since using ALSA emulation shouldn't cause programs to crash, even if it is suboptimal!  So perhaps this bug should stay open for now?

I tested it with openal-soft-1.10.622-6.0ceaa01c3de75c946ff2e7591e7f69b28ec00409git.fc12, no changes in .alsoftrc and warzone is not crashing any more.

New warzone2100 from testing repository works for me. Thanks!
