Crackling Sound Error

Question

When I had Windows 7 I had to limit the available RAM to 3GB maximum or I'd get crackling sound whenever a sound tried to play. Something to do with the drivers for the Creative X-Fi sound card.

Now that I've changed over to Ubuntu the sound has started crackling again.

Mightn't there be a way to limit the available RAM like I had to on Win7? Or I have to buy a new sound card?

You can control this with kernel parameters. If you follow the prompt to edit your Grub menu items when you first boot you can add parameters.

The mem and max_addr parameters would seem to be the most relevant.
