Aztech 16-bit in SB mode??

Aztech 16-bit in SB mode??

[lokesh setia]

Hi all,

I have a Aztech 16-bit sound card which reports to be SB16 compatible.
(In DOS that is, all games etc. use the SB 16  settings after the Aztech 
sound driver is loaded.).
I have a Redhat 5.0 with kernel 2.0.32, and i tried using sndconfig.
The card is not detected at io=0x220 (irq test fails at all irqs).
Then I came to know of LOADliN , i boot into dos, initialize the sound
driver, use loadlin to go into linux.
and voila, sndconfig does report my sound card and also plays the sample 
file correctly.

Now my problem is that my sound card is *probably* working in 8-bit 
mode. (the ioctl SNDCTL_DSPP_SAMPLESIZE returns the value 8 in the 
argument size, always).
I also tried using a software like vplay (distributed inside sndkit, by 
Hannu Salovien) but it says the following:

Unable to set 16-bit sample size, playing 8-bit.

If my card is detected correctly as SB16, then why does it play only 
8-bit?? Any Clues???

Hi

I think I may have the same card. (or similar) The sb emulation is only 8
bits. almost all cards which emulate sb only work in 8 bits. You need to
use the mss. Try using the sgalaxy driver, it works great for me. I use :

modprobe sgalaxy io=0x530 irq=7 sgbase=0x220 dma=1 dma2=0

Look at your autoexec.bat file, it will probably set galaxy= something.

Unless this is some very new card (last few months), there exists no
SoundBlaster 16 clones.

I have an Aztech Sound Galaxy PRO 16 card, which I used before getting my
genuine SB32, and it was a good card. 

Most cards which claim 16-bit sound mode usually use something like
MSS/WSS, and have a SoundBlaster PRO mode. 

An interesting thing about some of the Aztech's (mine included) is that
they ran both 16 and 8-bit modes at once...(at least the DOS-sided driver
did, I could never get it to work this way under Linux, had to be one or
the other).

If it has an EEPROM / software jumper, set it for EEPROM and make sure the
correct values are in memory, and then you won't need to use LOADLIN, just
boot it straight to Linux.

Thanks for that, but i could'nt get it to work ;-(
I'm sure i have almost the same card as you have.
(Aztech 16-bit Sound galaxy pro), 
It is compatible with both sb16 and mwss. and sets galaxy=foo in 
autoexec.bat.

Here's my problem now:  
First of all, this module (sgalaxy.o) isnt there in 2.0.32.
So i upgraded it to 2.0.36. then i removed everything from 
/etc/conf.modules and restarted the computer. Here are some 
results i got.

bash# lsmod
bash# modprobe sgalaxy io=0x530 irq\x11 sgbase=0x220 dma=1 dma2=0
/lib/modules/2.0.36/misc/sgalaxy.o: device or resource busy
sound: device or resource busy.
bash# lsmod
ad1848  blah blah
soundlow blah blah
soundcore blah blah
sound	blah blah
bash# rmmod ad1848; rmmod soundlow; rmmod sound;
bash# lsmod
soundcore (used by 0)
bash# rmmod soundcore
soundcore: device or resource busy.

You get it? i remove all instances and the sound is certainly not being 
used still i cant remove soundcore. and yes i have tried different irq's 
(5, 7 , 9 and 11) and io=0x530 (as in dos) but all i get is device or 
resource busy.

Infact, i get this device or resource busy on trying to load any sound 
module (pss.o, sgalaxy.o or whatever).

Did you need to recompile the kernel to get your sound card working?
Also, in my DOS setting there is no option for mwss irq no.. I heard
that irq\x11 is the default, but isn't it used by the display.

Thanks anyway.
