Hi all!

I recently installed Ubuntu 11.04 as a dual-boot with Windows Vista on my laptop via the Wubi installer. Now, for the past few weeks it's been working perfectly - however, just a couple of days ago, the sound mysteriously stopped working. I know it's not a problem with my laptop's speakers, because it works fine when I boot with Windows Vista. In addition, playback is working oddly - Youtube videos are sped up by about 2x or 3x. The same happens when I try to play music in a media player.

Anyone know of a fix? Thanks in advance.
