Switched from setting the period size and count to setting the buffer size directly, based on feedback from the ALSA development list: http://mailman.alsa-project.org/pipermail/alsa-devel/2009-October/022267.html This has the nice side effect of reducing latency on my SBLive! card.

28 When the mouse leaves or enters the window area a \fBSDL_APPMOUSEFOCUS\fP type activation event occurs, if the mouse entered the window then \fBgain\fR will be 1, otherwise \fBgain\fR will be 0\&. A \fBSDL_APPINPUTFOCUS\fP type activation event occurs when the application loses or gains keyboard focus\&. This usually occurs when another application is made active\&. Finally, a \fBSDL_APPACTIVE\fP type event occurs when the application is either minimised/iconified (\fBgain\fR=0) or restored\&.
