From b3d7615f2a012c5e589209d08e89c4116134c9f4 Mon Sep 17 00:00:00 2001 From: Giridhar Maruthy <giridhar.maruthy@linaro.org> Date: Wed, 13 Jul 2011 16:52:06 +0530 Subject: [PATCH] ASoC: SAMSUNG: 24-bit audio playback on Exynos4210 Using 256fs or 512fs will result in distortion of 24-bit audio samples. This is because the lrclk generated is not proper. Using 384 fs generates proper output.
