A properly written alsa backend requests the settings that it wants, but takes into account what values are actually returned.
It basically works like this:
Set this parma as close to x as you can. OK, I actually got y as a return value so I'm going to take y into account and not automatically assume x.
A user can override the parmas so that if an app say requests a buffer size of 0.5 sec and I set the buffer size to 1 sec the app will get that as a return value and that's what alsa will actually use regardless of what the app wants.
