[Openal] linux pitch/loop issues (again)

[Mikko Rytkönen]

First of all, I'm sorry to bring up this issue again as I found a couple of
related posts. None of them helped solve my problems..

I first downloaded the latest OpenAL source from openal.org, compiled, and
everything was fine until I tried changing pitch of a looping sample
(vehicle engine sound). Every time the sound repeated, there was a loud
click. After googling for a while I found that this is a "known issue" with
Linux OpenAL. I applied a patch that I found here:
http://opensource.creative.com/pipermail/openal-devel/2006-May/004326.html.
It seemed to fix the loop-click problem.

Now the problem is that if I change the pitch on any non-looping sample, the
application starts randomly crashing. Debugger shows that the segfault
occurs somewhere in al_filter.c (pitch filter). It might be that the patch
was faulty and caused the crashing. I will soon try to verify this by
testing the non-patched version again.

Has anyone managed to get OpenAL on Linux working with both looping and
non-looping samples while adjusting pitch? Any help would be appreciated..
