From 8565f052c5f696ba095a078ea7dbac32460012be Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 20 Dec 2012 12:54:18 +0100 Subject: [PATCH] ALSA: hda - Fix wrong dirty check in snd_hda_codec_resume_amp() The dirty entry has to be checked at the beginning in the loop, not in the inner loop for channels. This caused a regression that the right channel isn't properly written.
