Using foobar2000 0.8.3 (Jun 28 2004) on Windows XP Pro x64, there is noticable beeping during playback of m4a (AAC) files. It is seemingly random (not at the same place each playback).

I'd like to think this is a compatibility problem with x64, since I have no problems with the same configuration and plugins on my other machine (XP Pro), but I am not 100%. Has anyone else experienced this problem? Is it known/fixed in 0.9?
