Why number of buffer notifications (and therefore packets in the
buffer) is limited to 2? With more notification points, a driver could
use a single buffer to store captured data and communicate with
a client, and a client could optimize data retrieval.
You can have that with 2 notifications aswell. Actually, I've never understood
how it is possible to have anything else BUT 2 buffer notifications, as that is
the most optimal case, i.e. you get a notification for each half of the
circular buffer (which is how ASIO works), and it is easy to fetch/put data to
the buffer.
If you have more than 2, it only adds additional complexity without added
benefits.

Ps. Btw, how is one to interpret a notification count of 1 ? In this case there
surely must be buffer under/overflows all the time. I've never understood this.
