Description Sam Varshavchik 2002-08-19 04:06:00 UTC 
Description of Problem:

The audio output on the following chipset is full of popping and clicking at the
beginning and/or the end (most of the audio output goes through, but the
beginning and/or the end is full of popping and clicking).

It seems like the popping and clicking occurs whenever /dev/dsp is opened or
closed.  I ran a java applet game, and audio remained perfectly clear for the
duration of the game.  The java VM opens /dev/dsp and holds it open until the VM
shuts down.  The audio from java was clear throughout the gameplay, except for a
loud pop when the java vm started up (and no audio is played).


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

2.8.15-5smp

How Reproducible:

Always

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
