*** I posted this in the comments of the guide sticky post, but there weren't any responses. ***
I have a strange issue that I've been trying to resolve, and I've not yet been able to find a solution. I've gone through the guide, and it didn't help.
My sound is choppy/loopy. Ubuntu 8.04. As soon as you hit the login screen, the drum sound starts looping. You log in, and it goes away. Then, if you try playing another sound file, that file starts looping. If I do speaker-test, the white noise loops. The odd thing is, it actually progresses (gradually) through whatever the sound file is. So take the drum sound for example... it plays 1/2 of a second of sound, loops back, then progresses about 1/10th of a second into the file, and plays another 1/2 second. (At least, this is how is sounds). I had an MP3 running for hours, and when I came back it was about half-way through the song.
Another thing - it hasn't always been this way. I've not changed hardware. I've not recently upgraded Ubuntu. In fact, I can't think of anything I've done differently.
So, here are some of my outputs...
