From df86d1149f4b7b77158755b85b85f94e7bade32f Mon Sep 17 00:00:00 2001 From: Heikki Lindholm Date: Fri, 23 Nov 2007 15:37:48 +0100 Subject: [ALSA] add number of periods constraint to snd-aoa The aoa driver is not specifying constraints on number of periods, and, it seems, it might end with a non-integer number, which it cannot deal with. Fix by adding a proper constraint.
