From 75b46c1321785c29cfbc4f839b6dc031428734ad Mon Sep 17 00:00:00 2001 From: Jon Smirl Date: Tue, 15 Dec 2009 20:53:44 -0500 Subject: [PATCH] ASoC: Fix disable of SPDIF on STAC9766 codec Change code so that switching to playing music through the analog output disables SPDIF out instead of disabling it when stream ends.
