Summary:                    snd-ens1371 hisses and garbled sound
Description: 
Please see Debian bug
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=239575:

    http://bugs.debian.org/239575

The submitter writes in part:

------------------------------------------------------
Before installing [Debian] sarge I happily used the ALSA sound system on a
2.4.20 [kernel] with my SB PCI 128 soundcard. With the 2.4.24 kernel [...]
the following problems occur:
After initilization of the snd-ens1371 module a loud hiss comes out of the
speakers. The artsd fails and displays a message that it will use the null
output device. All ALSA or arts enabled apps either crash, remain in a
infinite loop  initializing or start with sound disabled.
------------------------------------------------------

Another person adds:

------------------------------------------------------
Sound system is working rather properly but I get continual hisses out of
my soundcard, some sound is coming out as well but is completely garbled.
------------------------------------------------------

Any idea what might be wrong?

Consider that the problem is currently solved, so I don't know if there 
is anything to see. BTW: I had to shutoff IEC958 for all users, that 
might show that, in deed, it's a KDE problem!?

Yes, it's a KDE issue which turns on the IEC958 control.
This is off default in ALSA.
