As far as I know 44.1 khz is the standard for CD. After too much time searching it's the reason I came up with. Looking at jack-devel archives it was a heated debate to have jack use anything that wasn't n^2. It looked like they decided to support it, but at least the version of jack I have doesn't yet. Once again though, I barely understand it myself. I looked for a link that was straight forward in explaining it, but no luck. Maybe someone else here can explain it better. Seeya digger
