I've tryed all of tips at this forum and there is still no sound at rear out jack.
The native Creative driver enables the rear out, so the problem is in kx driver, not in hardware.
Maybe the problem fixed in 3538 beta or there is another way to fix?

radu4u · Aug 16, 2004, 09:27 PM

I buy a sb0220, I tried original driver but it really suks, but the rear an subwoofer works fine, I tried kx drivers and I was very impress for the sound qualitty, but the problem is that my rear speakers and subwoofer doesn't work. When this bug will be fix, it is know this bug by the kx team?, will they try to fix-it? when. All respect for kx team

Does your center speaker work?

Because I can only get sound out of the 2 front speakers. (plus I can't even get the Creative drivers to install properly).

With the new alpha drivers the drivers at least finds the card and even gets the model correctly. The only thing is that I can't get sound from my rear speakers, the center speaker or the subwoofer..

No my subwoofer and center output dosn't work at all, no sounds the only output wich work is front left and front right. With my original creative drivers all the outputs work, but I don't have the quality of the sound wich is on the kx drivers, I wait for the new version hope that will be fix this problem

has anyone made to get sound from the rear from a SB0220?

MichalStach · Sep 16, 2004, 11:30 AM

I have the SB0220, and have the same problem-no rear sound. This card is detect by kX drivers how SB022x. What else?
I made all changes described on this forum, but still no rear sound

I'm think the register 0x5f is wrong. When I wrote 0x00 to it then it will disable front sound (nominal value 0x30 give front and center sound), but is still play!.

It will help somebody. This card constain Sigmatel codec: STAC9758. Datasheet is available on internet. The EMU procesor is: EMU10k1-JFF type.

I'm going to experiments today with other register by "kxctrl --gui" command.

Have any idea?

If value 0x00 disables center/lfe, then it is good register. STAC9758 is complex codec. If kx drivers do not touch some of it config registers, then if it is in default state and then it should work. Maybe you need to set volume for center/lfe channel in this ac97. Try to set ac97 register 0x36 to 0 and emu10k1 5f register must be 33

kxctrl -sac97 36 0

pzad · Sep 17, 2004, 07:03 AM

And if this doesn't work then try
kxctrl -sac97 38 0
too.This sets wolume for rear channels. I don't know if this sblive has swaped rear and center/lfe channels. Previous sb live uses rear ac97 output as center/lfe.

edit: sorry, register should be 38 (was 36)

Raka · Sep 19, 2004, 07:12 PM

Pzad, could you please describe what should I do in order to follow your suggestion? I'm starting with this drivers, hence I don't have no idea of what you are saying. It's something like -"execute this file with command" or something like that?

Thanks

MichalStach · Sep 22, 2004, 10:28 AM

Pazd You did mistake. I will write it again, register 5f (sptr 5f 0) don't control center or any other channel. I have tried write to it 0x00 but all available channels still paly.
I have also good information! For enable rear sound you will redirec register 0x64 on STAC97. Write on kxctrl:
'sac97 64 f600'

After that you have enable rear chanel, but it consist "copy(front sound)".
On SB022x rear and center are swaped too, but problem occurs because there isn't sound on rear (phisical center) chanel besides vol register 0x38.

How change it?

pzad · Sep 22, 2004, 11:56 AM

'sac97 64 f600' - this is not what you wanted

I didn't do any mistake. emu10k1 register 5f is correct and must be set to 0x33.

You are at stage where linux alsa users were 5 month before, but in linux alsa this card is working for 4 month now (all 6 channels).

Main problem is not STAC9758. Main problem is emu10k1. emu10k1 is connected to ac97 by ac97 link and you have to configure emu10k1 to send rear channels to ac97 (it will not do this as default - and this is set in register 5f).

set emu10k1 register 0x5f to 0x33
set volume in ac97 (maybe additional steps are needed too)
register 0x36 to 0
register 0x38 to 0

and rear outputs are on 0x0d and 0x0e of emu10k1 - this is diffent then on older sblive (old lives uses 0x08 and 0x09), you must setup you own dsp routing for rear channels.

MichalStach · Sep 22, 2004, 02:04 PM

OK! Don't be angry. I known a little EMU architecture. After entry 'sac97 64 f600' I switch rear outputs to signal from front channel, that is temporary solution, but for a moment work.
I will try today all Your tips
Thanks

pzad · Sep 22, 2004, 02:24 PM

I am not angry.

If you set register 5f and route signal (in DSP) to output 0x0d,0x0e, and you hear nothing from rear then problem is probably in ac97 config and try to play with it.

SB Live with this codec can be setup to disable route from analog to front speakers I think - this is just note.
