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? ====================================================================== ---------------------------------------------------------------------- jdthood - 11-02-04 21:27 ---------------------------------------------------------------------- One of the submitters added the following information. ------------------------------------------------------ [Using alsa-lib 1.0.6] Actually, I found a workaround to my problem under: http://www.mail-archive.com/gentoo-user@gentoo.org/msg39015.html It reads: > I upgraded to KDE 3.2 (also had an upgrade to alsa-driver .9.8) and afterward > had bad sound. (I have a Creative PCI 128 card, or something like that, that > linux identifies as an Ensoniq 5880, for which alsa uses the ens1371 card > drivers, whatever) > > If I turned up the volume (on the speaker) I got a lot of hiss and static on > the left channel. Even when I turned the volume in kmix all the way down > (should be just silence) I would get hiss, static and whatever was playing > (like a song on xmms) > > After trying a lot of complex things, the solution was pretty simple, click > the little Advanced box in kmix, and uncheck the button for IEC958. > That's what I did and it solved also my problem, though I would be pretty happy to have some explanations on the why. I tried also with alsamixer and (M)ute on IEC958 works as well, and the setup did survive an "alsactl store/restore" cycle. So it looks good for me. So, for me, the severity can be reduced. I do still think that the problem needs to be fixed (for new users), or at least documented.
