From b18c6c3c7768b7b81c2250bbccd0c3c0aed6b71f Mon Sep 17 00:00:00 2001 From: Lin Huang Date: Tue, 22 May 2018 16:53:42 +0800 Subject: [PATCH] ASoC: rockchip: cdn-dp sound output use spdif some monitors care about the parity bit in the sub-frame of I2S, but the cdn-dp always set this bit to "1", so these monitors do not have sound output if use i2s, use spdif can fix this issue.
