Thanks... so, I'm reporting again... with some extra info from a google 
search too:



-----------

With these kernel and alsa versions: The SB live! line's capture works 
fine
(it captures from both left and right channels)

Linux 2.6.11-1-386 #1 Mon Apr 25 01:18:07 UTC 2005 i686 GNU/Linux

Alsa version:

apt-cache policy alsa-base
alsa-base:
  Installed: 1.0.9b-4

apt-cache policy libasound2
libasound2:
  Installed: 1.0.9-3



------------------------------------------------------

Using these kernel and alsa versions: The SB live! line's capture works 
bad:
(it captures only from the line's left channel)

Linux 2.6.14-1-multimedia-386 #1 PREEMPT Sat Dec 10 16:52:12 CET 2005 
i686 GNU/Linux

Also with 2.6.13-1-multimedia-386 from aGNUla /DeMuDi

apt-cache policy alsa-base
alsa-base:
  Installed: 1.0.10-1

apt-cache policy libasound2
libasound2:
  Instalados: 1.0.10-1

-------------------------------------------------------
Here it fails too:

uname -a
Linux 030users 2.6.15.4-rt #1 PREEMPT Fri Feb 17 18:55:02 EET 2006 i686 
GNU/Linux

apt-cache policy alsa-base
alsa-base:
  Installed: 1.0.9b-4

apt-cache policy libasound2
libasound2:
  Installed: 1.0.10-2



--------------------------------

	Someone knows what is happening with this odd problem?

"
Problem: Selection an audio input source and selecting the input monitor 
option gives random results. After clicking some input and output 
settings in the mixer, I sometimes can record from a source, but often 
some other sound is mixed
with it. So recording cannot be used.
With the alsamixergui the settings can be set a little more specific, 
but the same problems occur.
The output does work for sounds created by programs, but selecting 
line-in or mic causes problems again.

My soundcard is a "Creative SoundBlaster Live 1024" (SBLive), which is a 
CT4830 (identical to CT4832). The EMU10K1 driver is used, and either 
selecting ALSA or OSS has the same problems.

This problem exists for some time, with all kernels and with previous 
Ubuntu versions.
Ubuntu: 5.10
Kernel: K7

Added info:
This problem seems to be with all Debian-based distribution.
The best way to test this, is to adjust the input gain and the selection 
of input channel, this has influence on the output (e.g. playing a 
MP3). The FreeSBIE and dynebolic LiveCDs do work with the CT4830/CT4832 
soundcard.

If possible, please upgrade to Dapper's 2.6.15-9 kernel. If you do not 
want to upgrade to Dapper, then you can also try the Dapper Flight 2 
CD's: http://cdimage.ubuntulinux.org/releases/dapper/flight-2/

Let me know if this bug still exists with this kernel.
