Summary:                    Support for SB Audigy LS Soundcards
Description: 
ALSA and EMU10k1 does not support the Audigy LS Card.
Only OSS/Linux support it but it costs. Is it possible to use the OSS
Drivers with ALSA? Or can anybody develop a working driver?

I am in the process of reverse engineering the Audigy LS, and there is
currently a audigyls driver in the alsa-driver CVS that can produce
sound.
As we don't have datasheets, progress is slow.

Can you send me a detailed installation tutorial for SuSE 9.1 Professional?
or your email/ICQ?
Iam not a professional so i need some help.

As you are "not a professional", I suggest that the best action to take is
to wait for the next alsa-driver release. Date for release is not set.

I just checked out the audigyls driver and it compiled. As I am writing
that, I am listening to a web radio via xmms and sound quality is pretty
good.
But I am having problems setting up capturing. I don't understand your
comments in 'audigyls.c':

"*    Notes on how to capture sound:
 *      The AC97 is used in the PLAYBACK direction.
 *      The output from the AC97 chip, instead of reaching the speakers,
is fed into the Philips 1361T ADC.
 *      So, to record from the MIC, set the MIC Playback volume to max,
 *      unmute the MIC and turn up the MASTER Playback volume.
 *      So, to prevent feedback when capturing, minimise the "Capture
feedback into Playback" volume."

I don't have any "MASTER Playback volume" to configure. After playing
around with it a bit, my system hung. I'm using gentoo, kernel 2.6.7. I
tried several configs with 'arecord -f cd test.wav' and 'aplay test.wav'
but couldn't get more than some noises.

Especially for J. C. Dutton i asked the Creative Open Source Department for
a Description of the Audigy LS Hardware he answered the following:

"Email: From: ghiebert@creativelabs.com | Re: Linux Audigy LS Card
Information needed

I'm currently working with the Creative legal department to create an NDA
for use by open source developers such as yourself.  The specification
would be released to an individual developer under NDA such that they
could create code based on the specification but could not re-distribute
the specification itself.  I don't know when this NDA will be available,
but I'm hoping that it can be ready by the end of August. 

Garin"

So at the End of August, you can ask him again to get the NDA for the
Audigy LS to develop a good working Driver much faster.
