Summary:                    Endless Pulsing/repeating sound clip emitting from
speakers
Description: 
As soon as SUSE pops-up a window or dialog box that includes anytype of
sound (ding, pop, boop, etc), a small piece of the sound gets repeated
through the ES1968 sound hardware in a repeating patter (typically about
14 times per 10 seconds). This repeating sound can only be terminated by
restarting ALSA, via booting, or configurint via YAST2 (which restarts the
ALSA). 
I searched the internet and found a SUSE-RPM for ALSA 1.0.10 and installed
it, but the problem did not get fixed.

Update from SnipePod 12/16/2005.
I have experiemented with the clock parameter on the ESS Maestro 2em per
the instructions for the SND-ES1968 on the ALSA-Project website. I have
tried every option, 0,1,2,3,4,5,6,7,8. Option 0=auto-detect and Option 1
were the only ones that allowed any valid sound through, but both option 0
& 1 had the repeating/oscillation sound problem discribed in the original
problem report. Clock parameters 2,3,4,5,6,7,8 would only create
screeching static type of sounds.

Identified Problem! Have a IOGEAR GPU202 USB 2.0 PCMCIA Cardbus card that
appears to have sometype of conflict (IRQ?). Had problems when installed
SUSE with my Netgear wireless card, that also was some type of conflict
with the GPU202. Installed SUSE fine when GPU202 was removed from
equation. Readded the GPU202 after successfully installing SUSE, but now
had the sound pulse problem. Had a hunch and removed the GPU202, restarted
ALSA, and the pulsing sound problem appears to have disappeared. Next, I
reinstalled the GPU202, and the sound pulse returned. Next, I decided to
swap Cardbus/PCMCIA position, beween the GPU202 and the Netgear wireless
(realizing that the Cardbus slots use different IRQs). Everything seems to
be working, good sound, wireless and GPU202. Will monitor and report back
if necessary. Cheers!
