Quake3 cannot output sound with ALSA

Message

vash · Post by **vash** » Sun Oct 13, 2002 4:16 pm

With kernel sound, Quake3 has no problems outputting audio. With alsa installed, I get the following errors:

Coult not mmap dma bugger PROT_WRITE | PROT_READ
Trying mmap PRO_WRITE
Could not mmap /dev/dsp

What do I need to do to get this going? If anyone needs some info, I'll gladly post to help get this solved.

Alsa is another kernel-level audio driver that provides the /dev/dsp. If OSS is working correctly, there is probably little need to use Alsa. (On the other hand, my sound card does not work with OSS, so I need to use Alsa to get my /dev/dsp.)

Double-check the settings in your /dev/modules.d/alsa file. Also, if you recompile the kernel, you must re-emerge alsa-drivers.

Did you mean 'arts', the KDE audio layer?

here is how to fix that

if you are using the cs46xx driver

options snd-cs46xx snd_index=0 snd_mmap_valid=1 snd-pcm-oss snd_nonblock_open=1

i think all you need is the "snd_mmap_valid=1"

hehe i am not even sure what th rest of that crap does

I have a sound card that uses the cs46xx driver and my sound works with everything except Quake3. I tried adding the options listed (options snd-cs46xx snd_index=0 snd_mmap_valid=1 snd-pcm-oss snd_nonblock_open=1) but it does not seem to help. I have put it in as it's own line and also I have added it to my existing 'options' line. Any ideas on why this would not work for me? I am getting the same error regarding mmap. I can play Quake3 but there is no sound. My sounds work in XMMS, UT (native), Diablo2 (using Winex), etc. In case you are wondering what my card is, here is the output from "cat /proc/pci | grep audio"

Code: Select all

    Multimedia audio controller: Cirrus Logic CS 4614/22/24 [CrystalClear SoundFusion Audio Accelerator] (rev 1).

I would really like to get this working with ALSA. Anyone with experience in getting this thing to work?

The latest version of ALSA (rc5) has changed the modules options syntax, dropping the snd_ form the start, so the option you want to pass while loading the modules is

mmap_valid=1

did you run update-modules after editing your /etc/modules/snd-cs46xx file?

actually I'm not 100% sure this will fix your problem, I'm having Quake 3 problems as well, but Return to Castle Wolfenstein works fine (indicating the mmap option is being loaded OK)

BonezTheGoon · Post by **BonezTheGoon** » Tue Nov 19, 2002 3:45 am

I corrected my problem. I guess I had a typing error or something when I had tried the earlier posted command in it's own line--or maybe I had placed it incorrectly. Here is the excerpt from my current /etc/modules.d/alsa which is working now just fine (no more /dev/dsp mmap errors)

Code: Select all

# ALSA portion
alias char-major-116 snd
options snd snd_major=116 snd_cards_limit=1
options snd-cs46xx snd_index=0 snd_mmap_valid=1 snd-pcm-oss snd_nonblock_open=1
alias snd-card-0 snd-cs46xx
# OSS/Free portion
alias char-major-14 soundcore

Sorry for the confusion. I swear I had already tried this config. Anyway thanks for the help!!

wow, they finally fixed it. i've been waiting for alsa to start working for ages now.

maybe now since im settled in to my apartment i can get started messing around with gentoo again.

TheCoop · Post by **TheCoop** » Sat Nov 23, 2002 7:36 pm

what about adding oss compatability? simply put 'snd-pcm-oss' into your modules.autoload

darktux · Post by **darktux** » Sat Nov 23, 2002 10:54 pm

RTFM, if you do it right, it's not necessary to put them on the modules.autoload...

/etc/modules.autoload

You won't have to edit this file for use with ALSA. After our rc-update add alsasound boot, our system will load the correct modules at startup.

It's not necessary to add snd-pcm-oss or snd-mixer-oss in this file. Check the this FAQ for more info.

This was taken from Gentoo Linux ALSA Guide.

BTW, Quake3 works like a champ under artsdsp using the -m option. Might solve problems if you run it that way.

void · Post by **void** » Mon Nov 25, 2002 11:42 am

I had the same problem...

I solved the problem by compiling alsa from cvs (cs46xx).
It works quite good now, but I still have some problems.
* Q3 won't start with TeamSpeak running.
* All soundlevels is reset at login (gnome-error?)

So ... Im using the intel8x0 module in alsa ... cant seam to get it to work with Quake3 . Get the mmap error on Quake3 startup. Ive tried alsadsp -m /opt/quake3/quake3 and that seams to solve the mmap error but instead I see this:

Sorry man it is a bug with the current ALSA drivers with regard to your intel8x0 driver. I had the same problem, finally bought a cheap $9 discrete sound card that uses the cs46xx driver.

Very interesting pounard. Maybe the intel8x0 bug is hardware specific. I was using the onboard sound on my ECS K7S5A and found many other posts on the web (not Gentoo) that indicated this was unfixed bug in ALSA. I had no reason to believe, when I commented earlier, that it did not affect all users using the intel8x0 driver. Many appologies! I do not know who all it will affect, but it did affect me! What hardware are you using X-SoCiaL?

On my system it always says 'sound system muted' but the sound works fine in the game

I had a similar problem..

/dev/dsp doesn't exist here with alsa... however, /dev/sound/dsp does.

in ~/.q3a/arena/q3config.cfg, changing the parameter snddevice to:

Code: Select all

  seta snddevice "/dev/sounds/dsp"

resolved it.

Hope this helps

Have the same issue with intel8x0 audio (i815 chipset).
So, in what package can I find alsadsp? Now "command not found".
And should I add OSS compatibilty?
What to do in steps (I only have alsa drivers, libs and utils)?

I use GNOME2. So, I should use esd.

Code: Select all

$ esd
esd: Esound sound daemon already running or stale UNIX socket

This socket already exists indicating esd is already running.

Then esddsp -m /path/to/quake/quake3 doesn't help.
Any suggestions?

Interesting I was wondering why my sound levels would never stay the same after adjusting them. I have a:

Toshiba Satellite 5105-S607
using the intel8x0 drivers I get same problem as far as channels keep reseting themselves. I'm using 2.5.66 Kernel as well with built in ALSA and get same error. Dayumm was hoping it was just dumb mistake on my part why it would always reset back...
