Extra information: I used an extra speaker, which works fine with another laptop by the way, but it has the crackling/rattling noise when playing back music.
Even though you're using UBUNTU I imagine that much like Windows, application volumes are sometimes not bound to Master volume. VLC player is one example of application not bound by Master. This has the potential to create an unclear or distorted sound like you would experience above hardware limits but at any volume where the input signal to system is higher than its input threshold via unbound software. I haven't had UBUNTU long enough to speak with any authority about drivers but you may find that it's something simple like an update. The UBUNTU forums are very thorough and you can probably find a post regarding similar problems there. You may also want to look at JIMCO's Laptop Audio FAQ at the top of the Laptop forum. Good Luck!

Jimco's audio FAQ definitely had useful information, especially for Windows users, but the audio problem on my laptop is most certainly caused by the driver.
I found out the problem completely goes away when the computer goes to sleep and comes back, and it's fine until I reboot or kill the sound driver daemon. I guess that works out for me for now, but I'd be happy to hear about the right solution to this.
