Frobozz: low buffer rates don't work either, and neither do rates in between.
My 24-96 files are all flac, and the 16-44.1 are a mix of flac, wma (lossy), and mp3.
When i play the 24-96 files in foobar, I see that my interface is syncing to 96khz with no problems, which leads me to think the problem might be with MJ. (Kristal, my recording program, also works fine at 96khz). I'm not using dsp or anything, just volume leveling, and even with that turned off, the same thing happens.
JimH: I've heard of ASIO4ALL, and I think I might have tried it before (don't remember what happened, although if I uninstalled it, chances are it didn't work). Is ASIO4ALL truly ASIO, or is it just a way of simulating ASIO for soundcards that don't support it? In other words, would I be losing any audio fidelity by using ASIO4ALL instead of my native Line 6 drivers? Is it still using the WDM drivers, or is it totally ASIO? I'll try it though, and see if it works.
