Never mind, I finally got it to work with as little sample buffer as 128
samples @44.1K so it
means < 3 ms, on a cheap laptop :) Actually WaveRT is a lot easier to
deal with than WaveCyclic.
Just a thought... when querying the driver for a buffer with notification, I
can choose 1 or 2 notifications per buffer.
Why 1 ? It is completely useless. To be able to fill up the buffer in time, 2
notifications per buffer is a minimum (?)
And a question on implementation of the position register: for my audio device
the position register is not wrapped with the
buffer size (i.e. it counts upward continuously), which does not seem to be as
the WaveRT spec suggests ?
And it can return a position not on a frame boundary, i.e. not a multiple of
wfx.Format.nBlockAlign. Seems odd to me...
