It turns out that the buffer size you
get, is not evenly devided by period size.
18645 % 4661 = 1.
That (wrongly) triggers the warning.
This may very well be an alsa bug, or
may not, but the code in the driver is
handling that properly, so there is no
need for such a verbose warning.

The attached patch shuts down the warning.
Takashi, could you please apply?
