I finaly got my linux desktop install working. Im running kubuntu 5.10 x86_64. i installed the nvidia drivers viathe visual apt-get interface. Sound is working.

I can start and run nexuiz, but the sound is dealyd alot, somethling liek 0.5 secs. i satrt nexuiz with -sndsterio -sndspeed 48000 (w/o the -48000 the sound is messed up)

Im not 100% sure, but i think the controls are laggin too..?

I've got that sound delay problem too if i run the -sdl in windows

A thing worth trying would be to compile the -glx version of the engine your self. This sounds like some problems with sdl as there are quite a few people with this problem and the -glx version helped there. However it would be even better to find a fix for sdl . I have to get my linux to run Nexuiz too next week when i have vacation

You can try to create a file ~/.asoundrc and put:

Code: Select all

pcm.!default {
        type hw
        card 0
        device 0
}

in there...

That might fix the delay (at least it does on some of the fedora machines at my university).

That fixed the dealy in a maffia kinda way.. it silanced it alltogether xD

Code: Select all

^7No available audio device
^7No available audio device
^7No available audio device
^7No available audio device
^7No available audio device
^7Failed to open the audio device!

Hmm i have seen such errors that were fixed by KadaverJacks ~/.asoundrc. Hmm do you have two sound cards installed?

yes, onbord nforce3 sound and a creative something. i use the onvord for gaming (the creative one as a old bord, i just use it for skype)

Just an idea, maybe

Code: Select all

        card 0
        device 0

has to be changed then.. Kadaverjack might know more.
I have linux running at home but currently only as a server as i did not yet find time to install those ati drivers and i DO NOT want to run linux without nexuiz so i did not yet have to play around with those things.. But this docu might help: http://www.alsa-project.org/alsa-doc/do ... oundrc.php

Yes my thought too, ill have a look at that link later and see what i can cope up with. i guess its abt time i learn how to set up a linux desktop machine properly

I also have a pretty annoying problem with sound:
Sound is scrambled and I get a strange echo. This happens with differend kernel-, alsa-, sdl-, and Nexuiz versions.
I did not find a solution for it, but I get almost acceptable sound with setting
_snd_mixahead "1000" and running Nexuiz with a really strange -sndsterio -sndspeed 24000.
My soundchip is a VT8233/A/8235/8237 AC97. Setting differend dxs_support-options also doesnt change anything.

I also compiled the glx version myself, because of a problem with glibc 2.3.6, but that also didnt help. The sound is now always that badly scrambled/has echos that I had to turn it off completely.

Have you tried the parameters "-sndspedd 48000" and/or "-sndstereo" yet?

I would suppose so as he even tried some really strange values

Yes I did. Also the .asoundrc, posted here. That also didnt help.
Also the sdl-version does not produce any sound. Ill check wheter this is a compilation problem (missing libsdl-mixer-dev package or so).
Yes, forgot libsdl-mixer-dev package. Sound works perfect, but only 2/6 channels are active. -sndstereo is needed to get unscrambled sound.

I don't have much linux experience, but perhaps you could try compiling with an alternative sound mixer?

I believe it would be "make cl-nexuiz DP_SOUND_API=OSS" where ALSA is likely the default, OSS is another option to try.

tZork, Why do you have both soundcards enabled? do you really need ehm both?
one was onboard and the other is ???

In most cases the onboard soundcards are lacking mmap function and thats why there are a lot of problems. If one uses something like a Soundblaster live or newer this problem should go away. I would recomend trying to disable the onboard card and then maybe try KadaverJacks fix again.

Another trick that may help:

Code: Select all

$ export SDL_AUDIODRIVER=dma


or

Code: Select all

$ export SDL_AUDIODRIVER=oss


before starting the SDL version. This goes over ALSA's OSS emulation and skips .asoundrc and similar files.

Need is maybe the wrong word, but i do use them both. mainly i use the addon card for skype and the onbord for everythign else. True thet onbord's usualy aint the best things under the sun, but it does work fine in windows so it should be possible to make it work fine in linux too. I havent had time to debug this stuff eny futher lately, hope i will get some time to do it next weak or so.

Are you using Arts (the KDE sound server artsd - is it running)? I run Nexuiz 1.5 on OS X and notice a slight delay for the sound on item pickups, but virtually no delay at all when firing weapons etc. - this is an SDL version.

If you have any sound servers running on Linux, they can sometimes interfere with the otherwise normal operation of the sound subsystem. For example on KDE usually artsd is enabled by default, and in Gnome there is usually esd. If either of those is enabled or running, try disabling (or just killing them). There's a control panel for Arts in KDE that lets you do this, for ESound you may need to use the gnome config editor to change the value (or add it) in a gconf to disable an auto-start of esd.

You try those already?

I had the same problems with my sound (0.5 seconds delay)
But i have only 1 soundcard ( only onboard sound ).

I'm running Nexuiz on Linux ( Ubuntu 6.06 64-bit ).

the sdl-version (the default in the startscript) has this strange bug, but
the glx-Version works fine for me.

Whith WindowsXP ( same machine ) i have no problems.

There have been changes to the SDL library so that those sound lags should no longer appear. So a update of your linux distribution should fix that bug. The next Nexuiz patch will ship a new version of the lib for windows too..
