My computer comes with an Avance Logic ALS100 sound card, i was
wondering if it is possible to set it up under linux, or if i should go
out and buy a sound blaster. I know all the settings like irq, dma, etc.

I'm running both redhat 5.1 and slackware 3.5.

The ALS100 chip is a decent SB16 clone.  Configure the driver just
as you would do for a real SB16; mine is at i/o 0x220, irq 5, dma 1,
dma16 5, mpu_io 0x330, and the opl3 is at i/o 0x388.
If you use a recent 2.1.xxx kernel, or Alan Cox' modular sound patch
for 2.0.3x, the card will be identified as ALS100 in /dev/sndstat.

Some people may need to initialize their card, either warm-booting
via Win95 or using isapnptools.  I can't tell you how to do that
since my ASUS T2P4 BIOS does it all for me :-)

1. Avance Logic ALS100 Sound Card DMA8Bit!

I got that sound card ALS100+, which is supposed to be 100% SB16
compatible, but the thing is that it is not!

All because it uses 8 Bit-DMA-channel (0-2) for 16-bit sound rec/play.
I suppose that a 16-bit transfer is splitted into 2 8-bit transfers...
As far as i know, my driver does not support 16-bit sound trhough
8-bit-DMA, (it sais: no valid 16-bit dma channel, only 8-bit sound
allowed!).
I read the source code of the SB16 driver and... (didnt understand
almost anything)... 8oP

So i would like to know if there is a driver that supports that
feature...

Please, email me as well as posting...
