Strange problem with alsa, emu10k1 and ut2003 on 2.6.3

Strange problem with alsa, emu10k1 and ut2003 on 2.6.3

[j.combes.ml]

Hello,

I have a strange problem with the sound on my PC [1] with the kernel
2.6.3 when I play to unreal tournement 2003. I use the same configuration
as the 2.6.1 which work quite well on my computer.

When I play to UT2003, sounds are not clean : there is some crackling.
Moreover, the music is played two or three time faster than normally. As
I haven't got this problem with 2.6.1, I imagine that it can be a problem
with the new alsa version.

I test to read some mp3 with xmms, it seem to work correctly.

any advices ?

[1] Athlon 2400+, VIA KT400, sblive, geforce fx with nvidia driver,
PREEMPT enabled.

Regards,
Julien

Music in UT2003/4 is in .ogg format.

I believe that some some of ALSA updates 2.6.2->2.6.3 broke OSS emulation,
ie. xmms works but eats 90-100% CPU.  I experience it with ens1371 driver.

I think it's the same problem, stay tuned...

It doesn't matter.

This is a problem with the openal.so library that comes with UT2003.  To
fix it you can replace it with one from America's Army or UT2004; or you
can just compile yourself a new one from cvs (www.openal.org).

I have tested your solution, it work perfectly.

Moreover, I test xmms with ogg like suggested, It works fine and doesn't
eat CPU in my case (it uses less than 1%).

Thanks to all.

Re: Strange problem with alsa, intel8x0 and ut2003/ut2004 on 2.6.3(all above 2.6.2-rc3)

Hi there,

I have ut2003/2004, and in both I can hear the crackling with kernel 2.6.3.
With 2.6.2-rc3 everything was fine.

I tried another openal lib (selfcompiled, armyops) but it doesn't help.
(I normally start my ut with "nice -n -1". If I start it with normal priority,
the sound gets a bit less crackling)
xmms works fine.

I have an intel8x0 alsa driver with oss support for my SiS chip
(P4 2.4Ghz/SiS645DX). And I'm using the nvidia driver for my GF card.
Kernel compiled with PREEMPT.

Regards,
Martin
