[AG-TECH] RAT with SoundBlaster Audigy problem

I completely agree with Adam's comments, Try using OSS and secondly, I
would see if using the plain old onboard sound works, as that is what I
had to do (Had to remove SoundBlaster live as I couldn't get it working
properly under Fedora Core 4).

I had that problem but with the integrated intel sound i8x0.  As soon as
switched to the OSS driver all was well.  Also, linux still seems to
some problems with the sound blaster live series drivers.  I have it on
pc at home with the live card and I still have problems with it
depending on
the application.

My two cents..

	I've been trying to solve the problem of our Linux A/V machine
crackly,poppy sound. Turning gain to almost nothing helps alleviate it, 
but it's still there when I play back a recording my sound or meetings 
via AGVCR. Everyone elses sound is fine (i.e. from the townhall), so 
it's not AGVCR. It's a 3Ghz P4, 1GB RAM, running kernel and a 
Soundblaster Live! card. It's running Debian Sarge with ALSA installed 
and the appropriate driver in the kernel (EMU10k). ALSA OSS API support 
is also enabled too.
	I thought I would try using a different soundcard, a
Audigy to see if that made any difference, but then I was unable to 
start RAT - it failed with a 'elem->type == SND_MIXER_ELEM_SIMPLE' 
failed'' message. I wondered if my RAT was old and didn't support ALSA 
or something, so I compiled the CVS version. Now I get the following 
when I start RAT (it doesn't die, just keeps printing the message with 
no UI)

	Googling for this it appears that someone posted about this
long time ago (2001) and never did a final resolution, or if they did 
they never posted it.

	Anyone have any ideas what the problem could be? I'm thinking
SB Audigy under Linux for AG is probably fairly common so it's probably 
something simply and silly. I'm curious if anyone else has run into this

problem? Couple of output of some possibly pertinent /proc files added
