Beeps during mp3 playback with xmms

[David Paigen]

Hello, all.

I have most (all?) of my music library converted to digital
format and I listen to one huge playlist using Xmms.  Recently
the audio quality has gone down considerably.  It used to be
rather good.

There are beeps at various tones inserted into the music.  
If I replay that section of the track, I do not hear the beep 
again.  There seems to be a slight correlation between the beeps
and mapping/unmapping windows, but not always.  Maybe this has
to do with paging or swapping?  It is not related to mouse movement.

The only thing I can think of that has changed is I added more
RAM to my machine.  Of course, I may have installed a new
version of xmms, and who knows how many libraries have been
updated during that time.

I am running FreeBSD 4.6-RELEASE, Xmms 1.2.7, esound 0.2.29.
Here is the boot line for my soundcard (I think it is a SB32):
pcm0: <CMedia CMI8738> port 0xc000-0xc0ff irq 5 at device 19.0 on pci0

This audio is really annoying.  Does anyone have any suggestions
for me?  Anyone ever hear anything like this?  Does anyone have
a better solution to suggest to get hifi audio out of my computer?

Thanks,
