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.

Check the kernel message whether via82xx informs about dxs_support option. 
If you don't see it, the proper dxs_support value is already defined in
the driver.  Otherwise, you'll need to set it manually.

In most cases, dxs_support=4 (5 is better in 1.0.9 release) should work. 
With the old boards, you might need to set 1, but this must be rare.

Once you set dxs_support=1, 4, or 5, this sample rate problem won't happen
any more.

I don't have a via card, that solution just lets via cards work with sample
rates other than 48khz, thus working around this issue, but not actually
fixing it, as it's an issue with quake's resampling...
