Sound Issues (Crackle) with Enemy Territory, Alsa-OSS and DMIX

[hitman_et]

Hi,
I have an onboard intel8x0, and alsa version 1.0.10. Everything is set up including dmix, i can run multiple xmms instances and everything works fine, both using alsa output and oss output ('aoss xmms').

The problem arises when i try to use Enemy Territory (any quake3 game for that matter), through aoss. I can only hear glimpses of sound and that crackles pretty bad.
ET startup stuff:

------- sound initialization -------

# cat ~/.asoundrc
        pcm.intel8x0 {
           type hw
           card 0
        }

        ctl.intel8x0 {
           type hw
           card 0
        }


pcm.dsp {

# mixer0 can stay unchanged, because
# it isn't used anyway, I guess ;)
ctl.mixer0 {
    type hw
    card 0
}

cat /proc/asound/card0/pcm0p/sub0/hw_params

access: MMAP_INTERLEAVED

Any help is appreciated.
Thanks

After some more research I believe the problem lies in the fact that ET uses mmap'ing to access the OSS device files.
Any Ideas?
