[ut2004/Armyops]How to enable 5.1 sound with OSS(no ALSA)

[Stolz]

Hi.

I've read lots of post about enabling 5.1 with alsa for games that use OpenAL sound system(UT2003, UT2004, America's Army,...) but , What should I do to get 5.1 works with my SB Live! using emu10k1?

All games play the same rear and front speakers, no 3D or 5.1 sound

Any suggestions?

Thanks in advice.

I don't think it's possible with oss; the emu10k1 ALSA driver works great here with 5.1.

I'm using a SB Live! 5.1, Kernel 2.6.5 with alsa support in the Kernel (mark as module).

1.-I've emerged openal-cvs, linked both libSDL and openal fom [gamedir]/System to /usr/lib/.

2.-I've created ~/.openalrc:
(define devices '(alsa))
(define speaker-num 4)
(define alsa-out-device "surround40:0,0")

3.-With the alsamixer, I've mutted SB Live Analog/Digital Output Jack and Sigmatel 4-Speaker Stereo, and set the correct controls to the spected values.

4.-I'v tested alsa with XMMS and all 5 speakers work fine, with XINE I can distinguish the 5 chanels sound in AC3 films.

5.-Other games sound great (chromium, ET, racer, tuxreacer...)

So I suppose ALSA is working fine, but I'm still unable to get 5.1 sound to work with America's Army, UT2003 and UT2004

When runnig a game I can see /dev/snd/pcmC0D0c failed: Device or resource busy. I've solved it typeing killall artsd before launching the games, but 5.1 still doesn't work. Rear speakers don't play any kind of sound, and front speakers play the same as the central one, so there is not stereo or not even a poor 3.0

Conclusion: Using ALSA, I am only able to obtain a miserable 1.0 (but listened through three speakers).

Thats the reason I want to know how can I get 5.1 sound using OSS (emu10k1)

I would apreciate as help as possible.

Thanks in advice.
