DVDA 4.5b absolutely won't play back rendered audio files at the proper speed through my RME Digiface. Everything is set to 48k, but it's playing back the files as if they were at 44.1. Switching to my auxiliary Soundblaster card, speed is fine. Any ideas? I've always been baffled that DVDA doesn't allow sound card output routing selection and is subject to the default Windows setting---especially since QuickTime is always messing with that.
