The buffer size for SDL is set to 2048. Setting it to 256 added a slight ~1.0 frame per second and switching it to 32768 basically cut the entire frame rate in half. Various combinations of all the other audio settings didn't seem to make any difference, and none of the audio settings changed on OpenAL made it run slower.
Unfortunately, I don't have access to a computer running Windows 7. I ran Blender on compatibility mode's Windows 7 but the SDL audio device still caused AV-sync to lag. I don't remember exactly why or when my default was set to SDL because I've been using a custom startup file for nearly a year, but I'm guessing it's because I was trying to see how it differs from OpenAL and forgot, or didn't get the chance to switch it back before saving a new startup file.

Switching from SDL audio to OpenAL fixed the problem with both the timeline and the 3D viewport. But what could cause this problem with SDL's audio sync?
