Description of problem:
When playing mp3s in xmms (or for that matter, when using realplayer, and I
assume, any other audio software), after a while, static gets induced in the

The static only occurs after switch between virtual desktops in X.  Or
similarly, switching between browser tabs in Mozilla can also induce the static.
 Once the static begins, the only way to stop it is to close the audio playback
program and then restart it.  

The static usually starts occuring after about the 5th-6th desktop that I switch
between.  It is quite frustrating to be doing work while listening to music and
suddenly there exists a lot of annoying static in the music.  It is possible
that the static only gets induced when making frequent desktop switches.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Play an mp3 via xmms on RH8.0
2. Quickly switch virtual desktops while listening to music
3. After a number of switches, static will start occuring in the playback that
does not exist in the recording

Actual Results:  Audio static is heard through my speakers.

Expected Results:  Normal music playback with no static.

Additional info:

I am running RH8.0 on a Dell Inspiron 5000.

Something similar happening here, but I have VIA 686B.
Switching virtual desktops or X <-> console.
Sometimes it starts when switching, and sometimes
it *stops* when switching.
Oh, and this should be probaly filed against kernel, not xmms.

Some googling on this issue leads me to think this is a problem with ESD.  I 
should note that this problem also renders my system unable to play DVDs in 
any sort of sane fashion as the static is unbearable.

Apparantly fixed in 2.4.20.  At least, on my laptop running RH9, I no longer 
have any audio static problems.
