Umm..  I have no idea what that was supposed to mean..    A hardware 
device can generate interrupts whenever it wants.

The question was, why do you need software timers that have more than 
10ms resolution?  For a conference, is it really necessary to mix 8 
samples at a time?  -- It really doesn't help, especially when calls are 
VoIP, and are coming in at least 20-30ms frames..
