I do not have any other audio applications in which to test ASIO4ALL (to my
knowledge). However, other ASIO drivers do work at, for example, 22050 with
Csound5 - so the issue seems specific to ASIO4ALL.

I did try the lower SR's with Csound5Beta, as well as the most recent
CsoundAV. They do not work. However, I recall clearly that at an early point
in the Csound5 process (apparently pre-beta), the lower SR's were working
with ASIO4ALL. Perhaps Michael can shed some light on what may have
happened.

It would surely be wonderful if these rates were working again. It is not
*necessary* though, as they are working for both MME and DirectSound.
Earlier, when Csound5 *only* worked with ASIO, it was more of an issue (and
this was when the lower rates *did* work).
