Summary:                    Sound in Quake 3 does not work
Description: 
I already tried several things to get sound working in Quake 3. It doesn't 
work. Sound in other applications, such as xmms, works without problems.
My System: SUSE Linux 9.1 Pro 64bit, MSI K8T Neo FIS2R, Athlon 64 3200,
1GB 
RAM, VIA 8237 on board sound

I tried it with the ALSA version that comes with the Default Suse Kernel,
then 
with version 1.05a and at the moment I've installed a version from CVS two

days ago. I loaded the alsa module with dxs_support 0 to 4, that didn't 
resolve the issue.

Without changing anything in the ALSA configuration Quake 3 starts and the

game runs without problems, but there is no sound. The following error 
message is displayed when Quake 3 starts.
------- sound initialization -------
Could not mmap dma buffer PROT_WRITE|PROT_READ
trying mmap PROT_WRITE (with associated better compatibility / less 
performance code)
/dev/dsp: Input/output error
Could not mmap /dev/dsp
------------------------------------

Enabling direct access to the OSS playback device and disabling the OSS 
capture device with 
echo "quake3.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
echo "quake3.x86 0 0 disable" > /proc/asound/card0/pcm0c/oss
I get sound in the Quake 3 menu, but as soon as I enter a map the game
hangs 
and the only way to get back to X is to kill the process.

I also tried the user space ALSA OSS wrapper library. With this library I
only 
get some crackling noises in the menu and in the game.

With xrun_debug 1 I get a few of the following messages (at least with the

actually installed drivers from CVS) in the system log. These messages are

also there when I run other applications than Quake 3.
Jul  8 19:07:48 mordor kernel: ALSA sound/core/pcm_lib.c:199: Unexpected 
hw_pointer value [1] (stream = 0, delta: -1024, max jitter = 8192): wrong 
interrupt acknowledge?
Jul  8 19:07:48 mordor kernel: ALSA sound/pci/via82xx.c:731: invalid 
via82xx_cur_ptr, using last valid pointer
Jul  8 19:08:00 mordor last message repeated 194 times

I don't know whether that has something to do with the problem.

Using kernel 2.6.7, i have a similar problem :

------- sound initialization -------
Could not mmap dma buffer PROT_WRITE|PROT_READ
trying mmap PROT_WRITE (with associated better compatibility / less
performance code)
/dev/dsp0: Input/output error
Could not mmap /dev/dsp0

After typing :
echo "quake3.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
echo "quake3.x86 0 0 disable" > /proc/asound/card0/pcm0c/oss
I get :

------- sound initialization -------
/dev/dsp0: Invalid argument
Could not set /dev/dsp0 to stereo=1------------------------------------

Have you tried seting the dxs_support options yet. In modprobe.conf try
adding 
"options via82xx dxs_support=4".
