Gnome sound events playback quality is "grainy" as if being constantly interrupted.

Description of problem:
I have installed FC4 on two different machines (one Dell 8600 laptop, another IBM Intellistation E Pro) that seem to use the same sound driver hardware, snd_intel8x0. In both cases, I have been able to get sound to work without much difficulty (although the laptop suffered from the 'enable external amplifier' problem) and all other sound apps work clearly and flawlessly. MP3s and video with audio work just as they should. However, any sound generated by gnome sound events, including sound from GAIM, gnome window/mouse events or shutdown all sound "grainy" and interrupted.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.Enable sound events
3.Play gnome sound samples
Actual Results: Any sound played through gnome sound events are grainy or interrupted.
Expected Results: Clear audio sample playback.
A solution has been found for my apparently common configuration (Intel sound
device + FC4/Gnome). In the FedoraForum someone offered the following:
Fix: edit /etc/esd.conf, and add "-r 48000" at the end of the "spawn_options"
line. Then log out and log back in.
Explanation: some sound cards (especially those built into motherboards) require
that you send sound to them at a specific sample rate. esd (GNOME's sound mixer)
apparently doesn't detect this properly. Adding the "-r 48000" forces esd to
send sounds at the right sample rate.
This problem should be fixed somewhere higher up in the chain of installation
events though I'm not sure where it should be. The fix required that I reboot
rather than log out, however.
This report targets the FC3 or FC4 products, which have now been EOL'd.
Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?
The problem did not present itself in FC5 or FC6.
