I'm still getting a non-cleared buffer played a bit louder/incorrectly/not-in-sequence when I start playing a AC3 music in .m4a files using the latest Hajo's 1.6.7 in Mac 10.10.1 in a MacBookPro 15 Retina. The buffered audio is clearly from whatever was playing when your engine was shut down because if I was playing a silent portion of a song when I closed the previous .m4a then opening the next .m4a with Quicktime X plays that silence (unnoticeably). But if I was playing a loud song before closing previous .m4a then opening the next plays an stray buffer with the previous song. So maybe you need to clear the buffer one more time when the engine detects that audio is coming into your genuine fake sound card (processing engine).
