           Summary: Soundcard CT4832 (SB Live) has wrong input/output
                    selections
           Product: Ubuntu
           Version: unspecified
          Platform: i386
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel-package
        AssignedTo: ben.collins at ubuntu.com
        ReportedBy: jdorsman2004 at hotmail.com

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
