[Xpert]Noises during playing sounds

[Antonio Bibiano]

When I play some sounds and I move a window or scroll a page I ear some clicking 
noises, I have a sound blaster live! (with ALSA module snd-card-emu10k1) and a S3 
Savage 4 using the X driver "savage" for the XFree86 4.2.0 .

There is some reason to my problem??? 

Can you give me some help??

Thanks

Antonio

Turn down/ mute your audio in and mic.

You probably have one/both of those maxed and as a result they are picking
up electrical interference from using your mouse or other things and
amplifying it a _LOT_ and outputing it. The alternative is to turn off
loop back on either/both of these. This would allow you to still use the
mic, but then audio coming in to the mic/aux_in wont also come out your
speakers, it will just go to the application recording them.

I've honestly never seen this on linux but I have seen it on several
windows computers. And as far as I know this is the only possible way for
your moving the mouse to generate static in your sound card.

As allways, I don't guarantee I'm correct though.

Good luck.

Actually, I don't think he said that just moving the mouse causes the 
problem. It seems like it's happening whenever he scrolls a window or 
moves it.

If the S3 card is PCI, chances are it's stealing PCI bandwidth from 
the SBLive! card causing this audio "tearing." If that's the case, 
there's really nothing you can do about it (except buy an AGP video 
card)! I would suggest turning off "opaque window resize/move" in the 
window manager if it's enabled, that should reduce the PCI bandwidth 
requirements during a window move/resize. However, scrolling will 
probably continue to cause clicks and pops.

I had precisely this same problem back when I was also using an S3 PCI 
card. There's no good solution except to upgrade to AGP if possible.

The PCI bridge can be put into a special mode allowing infinite retries.
This means that if the video card is given a command, the PCI bus
essentially stops until the video card responds (and some video cards take a
long time to do so).  Some X servers will allow you to turn this particular
feature off while still enabling the other acceleration abilities of the
video card but as to which X servers allow it and how to actually disable
this 'feature' I have no idea.

This is a problem that crops up quite regularly in real-time systems
requiring tight deterministic features (the video card literally blows
determinism out of the water) although I have not personally had to deal
with it.

Yes but I tried to install XFree86 3.3.6 and the problem was resolved but with the 
3.3.6 was a luck of libraries and some programs asked me libraries that I had to take 
from the 4.2.0 directory and becuse some of the programs that I abitually use doesn't 
run I came back to XFree86 4.2.0

Why with 3.3.6 there isn't any problem..???

and How I can install well it on a Salckware 8.1???

Can you help me??

   These are usually PCI retry problems.  Those happen when the graphics
driver sends data to the card when there is not room in the fifo.  In that
case a PCI disconnect occurs and the bus retries sending the data
until there is room again.  This has a distruptive effect on the 
performance of other cards using the PCI bus.   I don't know if this
is what is happening with the Savage driver, but what I described
is the typical cause.

  I am also faced is problem in my machine ( Intel 810 ). But after
  re-fixing [ Change the polarity - In AC polarity has no meaning :) ] 
  the speaker power plug, the clicking nosies stoped.
