If you're rockin’ out to polka on your headset, you can tell Yahoo! Messenger to also ring your PC 'squeaker'—the tiny built-in speaker inside most computers.

Here’s how to enable this feature:

1. Under "Messenger" in the upper-left corner, click Preferences.
2. In the category list down the left side, click Calling Devices.
3. Near the middle of this window, check the box next to Ring PC speaker.
