From 0aea778efa0d632b62eb35122cbb3b9fae548c61 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 25 Jan 2010 15:44:11 +0100 Subject: [PATCH] ALSA: hda - Remove the COEF setup for ALC267/ALC268 The COEF setup for model=auto seems problematic on some laptops, resulting in the silent speaker output. Better to disable it for now.
